Fermented Black Rice The K-Beauty Ingredient haruharu wonder Built an Entire Routine Around
Most K-beauty brands feature fermented ingredients as a supporting note. haruharu wonder made fermented black rice the through-line of every single product they make โ and there's a good reason why. Fermentation is one of those K-beauty concepts that sounds like a trend but is actually rooted in centuries of Korean practice. The fermentation of crops and botanicals for skin and health goes back to the Joseon era, where fermented rice water was used as a daily skin treatment. What's changed is the science: modern fermentation technology can now isolate and concentrate specific bioactive compounds from ingredients like black rice in ways that weren't possible even twenty years ago. haruharu wonder is a brand that has taken this idea and committed to it fully. Unlike many K-beauty brands that treat fermented extracts as one ingredient among many, haruharu wonder uses fermented black rice โ specifically, Oryza Sativa (Black Rice) Extract processed through their proprietary fermentation method โ as the base of their entire lineup. Every product in the range starts from the same place: the fermented grain that's been a part of Korean food and wellness culture for centuries. This week's G-log walks through three haruharu wonder products that are new to Nuriglow, plus a brief look at two others from the line you may have seen here before. Together, they build a complete routine from cleanse to treatment โ all built on the same fermented foundation. The haruharu wonder Routine haruharu wonder Black Rice Moisture 5.5 Soft Cleansing Gel โ $17.00 USD | 100ml Best for: All skin types โ especially sensitive, dehydrated, or barrier-compromised skin that dries out after cleansing A lot of cleansers that claim to be gentle still disrupt the acid mantle by washing at too high a pH, which leaves your toner and serum working harder to compensate. This one formulated specifically to avoid that: the pH is 5.35, which sits just below the skin's natural range and supports a healthy acid mantle rather than disturbing it. The surfactant base is coconut-derived (Coco-Betaine and Potassium Cocoyl Glycinate), which is a gentler choice than typical sulfate-based cleansers, and it creates a mild lather that lifts impurities without feeling stripping. Fermented Black Rice Extract and Bamboo Extract add the brand's signature antioxidant and brightening properties even at the cleanse step, while Beta-Glucan and Trehalose support barrier function and moisture retention through the rinse. The inclusion of Panax Ginseng Root Extract is worth noting โ ginseng is a trusted K-beauty ingredient for its antioxidant content and long association with skin revitalization. It's a small but deliberate nod to the brand's Korean botanical roots, and another example of how haruharu wonder layers purpose into what most brands treat as a purely functional step. Key ingredients: Fermented Oryza Sativa (Black Rice) Extract, Phyllostachys Pubescens Shoot Bark (Bamboo) Extract, Beta-Glucan, Panax Ginseng Root Extract, Trehalose, Coco-Betaine (coconut-derived surfactant) pH: 5.35 Best used: AM + PM ๐ก Pro tip: Pair this with a cleansing oil as your first cleanse to double-cleanse properly โ haruharu wonder recommends their own Black Rice Moisture Cleansing Oil as a pre-step for a complete oil-to-gel routine. ย haruharu wonder Black Rice Hyaluronic Toner Free of Alcohol Fragrance โ $18.00 USD | 150ml Best for: Sensitive, reactive, or fragrance-intolerant skin that needs reliable deep hydration without any potential irritants This is the alcohol-free and fragrance-free version of haruharu wonder's bestselling Black Rice Hyaluronic Toner, built for those who react to even the trace amounts of alcohol or fragrance often present in essence-type toners. It uses a highly concentrated essence-type formula rather than a watery base, which makes it feel noticeably more substantial than typical first-step toners. Fermented Black Rice sits as the primary active alongside multiple forms of Hyaluronic Acid for layered hydration at different skin depths. Bamboo Shoot Extract adds its own moisture-binding properties alongside antioxidant support, and Ginseng Root Extract continues the brand's consistent anti-aging nod through the line. The result is a toner that functions closer to an essence: plumping, slightly viscous, and immediately visible in how it affects the next product's absorption. For the sensitive skin community in particular, this has become a reliable staple โ it's free of alcohol, artificial fragrance, drying sulfates, mineral oil, and the full list of K-beauty 'seven free' criteria. The absence of those potential triggers doesn't make it a lesser product; the formula just puts the active ingredient budget toward things that actually help skin rather than things that make it smell nice. Key ingredients: Fermented Oryza Sativa (Black Rice) Extract, Sodium Hyaluronate (Hyaluronic Acid), Phyllostachys Pubescens Shoot Bark Extract, Panax Ginseng Root Extract, Bamboo Extract Best used: AM + PM ๐ก Routine tip: Apply two thin layers of this toner rather than one heavier coat โ the 2-3-4 skin method of layering lightweight hydration gives fermented actives more contact time with skin, which improves absorption versus one thick application that sits on the surface. ย haruharu wonder Black Rice Probiotics Barrier NAD+ Serum Mist โ $22.00 USD | 80ml Best for: All skin types looking for an anti-aging treatment step that doubles as a hydrating mist โ especially useful for travel or on-the-go routines A serum mist is a format you see occasionally in K-beauty but rarely executed with this much ingredient density. This one contains 2% NAD+ โ the cellular coenzyme we covered in last week's G-log on EQQUALBERRY's NAD+ line โ alongside a 5 Ceramide Complex, two strains of probiotics (Galactomyces Ferment Filtrate and Bifida Ferment Filtrate), fermented black rice, Panthenol, and Squalane. For reference, 2% is a higher NAD+ concentration than most leave-on serum formulas. The probiotics in this formula are worth singling out. Galactomyces Ferment Filtrate is one of the most well-studied ferment filtrates in K-beauty, clinically shown to improve skin radiance, reduce sebum, and refine surface texture. Bifida Ferment Filtrate specifically targets the skin microbiome, supporting the beneficial bacteria that maintain a balanced and resilient barrier. Together they form a probiotic layer that most serums โ and essentially all mists โ simply don't include. Functionally, it can slot into the routine wherever you need it: after toner as a serum step, over makeup as a midday refresh, or spritzed on during travel to rehydrate depleted skin. The ultra-fine mist format means it absorbs without disrupting anything underneath, which makes it one of the more genuinely versatile products in the haruharu wonder lineup. Key ingredients: NAD+ (2%), 5 Ceramide Complex, Galactomyces Ferment Filtrate, Bifida Ferment Filtrate (Probiotics), Fermented Black Rice Extract, Panthenol, Squalane Best used: AM + PM โ or as a midday refresh over or under makeup Want the Full Routine? Two More haruharu wonder Products to Know These two haruharu wonder products have been featured in depth in previous G-log articles. If you're building the complete routine shown in the table below, they complete it โ but follow the links to read the full breakdowns. ๐ Previously featured: Black Rice Probiotics Barrier Essence ($28 | 120ml) โ featured in our Glass Skin guide. The ceramide-forward essence that builds the barrier foundation the rest of the routine layers onto. A triple-ceramide complex (3:1:1 ratio), Galactomyces, and Bifida Ferment Filtrate for elasticity and texture. Read the full breakdown in our Glass Skin guide on the G-log. ๐ Previously featured: Black Rice 5 Ceramide Barrier Moisturizing Cream ($24 | 50ml) โ featured in our Mugwort & Pore Care guide. An encapsulated 5-ceramide moisturizer that releases into the lipid barrier on contact for targeted repair. Fragrance-free, pH 6, and compatible with every step in this routine. Read the full breakdown in our Mugwort guide on the G-log. The Full haruharu wonder Routine at a Glance Step Product When Key Concern 1 Black Rice Moisture 5.5 Soft Cleansing Gel AM + PM Barrier-safe cleanse + antioxidant prep 2 Black Rice Hyaluronic Toner AM + PM Deep hydration + elasticity 3 Black Rice Probiotics Barrier NAD+ Serum Mist AM + PM Cell renewal, barrier reinforcement 4โ Black Rice Probiotics Barrier Essence AM + PM Barrier foundation (see Glass Skin guide) 5โ Black Rice 5 Ceramide Barrier Moisturizing Cream AM + PM Seal + long-term barrier repair โ Previously featured products. Start with Steps 1โ3 if you're new to the line; add Steps 4 and 5 to build out the full barrier-focused routine. Why Fermented Black Rice Specifically? Black rice โ called 'forbidden rice' in ancient China because it was reserved for royalty โ is nutritionally distinctive among grains because of its exceptionally high anthocyanin content. Anthocyanins are the pigments that give the grain its deep purple-black colour, and they're also potent antioxidants with well-documented anti-inflammatory and anti-aging properties. The fermentation process takes those compounds and breaks them down further, increasing their bioavailability โ meaning the skin can actually absorb and use more of what the ingredient contains rather than having it sit at the surface. Fermentation also produces additional beneficial byproducts: organic acids that gently exfoliate and refine texture, amino acids that support barrier proteins, and postbiotics that contribute to skin microbiome balance. In practice, that means fermented black rice extract is doing something more complex than simply delivering antioxidants โ it's also refining the surface, supporting barrier structure, and contributing to the microbial environment that healthy skin depends on. For a broader look at how fermentation shows up across K-beauty brands and ingredients, our Barrier Repair guide and Sensitive Skin routine guide both cover products and approaches that share a ferment-forward philosophy. Final Thought haruharu wonder's approach โ building every product on the same fermented base, then layering complementary actives (NAD+, ceramides, probiotics, hyaluronic acid) on top of it โ results in a line where every product reinforces every other product. There's no ingredient conflict to worry about, and no step that feels like it belongs to a different routine. That kind of internal coherence is genuinely rare, and it's part of what makes the brand worth committing to fully rather than picking up a single product. Shop the full haruharu wonder collection at Nuriglow and find the routine that fits your skin. All products are available at nuriglow.com! FAQ Q. What is fermented black rice extract and why is it used in skincare? A. Fermented black rice extract is derived from Oryza sativa (black rice) through a controlled fermentation process that increases the bioavailability of the grain's natural compounds โ anthocyanins, amino acids, and organic acids. Fermentation breaks these down into smaller molecules that the skin can absorb more readily, making the antioxidant, brightening, and barrier-supportive properties more effective than unfermented extract. Q. Is haruharu wonder suitable for sensitive skin? A. Yes โ it's one of the more consistently sensitive-skin-friendly brands in K-beauty. All five products at Nuriglow are fragrance-free, free of drying alcohol, and clinically tested for low irritation. The Hyaluronic Toner and Cleansing Gel specifically are formulated to the highest sensitivity standards in the lineup. Q. What makes the NAD+ Serum Mist different from a regular face mist? A. Most face mists are primarily water or floral water with minimal actives. This one is formulated at serum density โ 2% NAD+, two probiotic strains, five ceramide types, fermented black rice, and Squalane โ in an ultra-fine mist format. It functions as a treatment step, not just a hydration top-up. Q. Do I need to use all five products, or can I start with just a few? A. The three new products โ Cleansing Gel, Toner, and NAD+ Serum Mist โ work well as a standalone cleanse-tone-treat routine. The Barrier Essence and Ceramide Cream add a more comprehensive barrier-repair layer and are worth adding as the next step if you want a full five-product routine. Q. Is haruharu wonder cruelty-free and vegan? A. Yes. haruharu wonder is certified vegan and cruelty-free. Their 'Better Vegan for All' brand philosophy extends to all five products currently available at Nuriglow. Q. Can I use the haruharu wonder line alongside other K-beauty actives like vitamin C or retinol? A. Generally yes. The fermented black rice base and the ceramide and hyaluronic acid layering in this line are compatible with most actives. If adding vitamin C or retinol, introduce them separately and patch test โ not because of the haruharu wonder products specifically, but as standard practice when mixing actives from different brands.

NAD+ Skincare: The Anti-Aging Coenzyme K-Beauty Is Already Building Routines Around
Before NAD+ supplements took over the wellness aisle, K-beauty labs were already formulating the coenzyme into toners, serums, and creams โ here's what it actually does for skin, and where to start. If you've spent any time on skincare or longevity TikTok in the past year, you've probably seen NAD+ mentioned โ usually in the same breath as supplements, IV drips, and cellular aging. What's gotten less attention is that NAD+ skincare has quietly been developing in Korean labs for a while now, formulated into leave-on toners, serums, and creams rather than pills or injections. That's a very K-beauty move. Korean formulators have a track record of taking ingredients with strong cellular-level science โ PDRN, peptides, fermented actives โ and finding a way to deliver them topically, then layering them with complementary actives so the whole routine works together instead of relying on one hero ingredient to do everything. This week's G-log covers a full NAD+ anti-aging routine built entirely around EQQUALBERRY's NAD+ Peptide Boosting line, plus one supporting product that fills a gap the NAD+ formulas don't cover. We'll break down what NAD+ actually does in skin, how to build the routine, and whether it's worth adding to what you're already doing. The NAD+ Peptide Lineup EQQUALBERRY NAD+ Peptide Boosting Toner โ 21.99 USD | 150ml Best for: First signs of sagging, dehydration, and dullness โ anyone starting an anti-aging routine from scratch This toner is the entry point to the whole NAD+ line, and it's doing more work than a typical first-step toner. Past the usual hydrating base, it's formulated with NAD+ (Nicotinamide Adenine Dinucleotide) alongside niacinamide and a 12-peptide complex, so the anti-aging signal starts at the very first step of the routine rather than waiting for serum. The supporting cast matters here: ceramide NP for barrier support, adenosine (a well-studied wrinkle-softening ingredient in its own right), and a blend of pomegranate, blackberry, blueberry, raspberry, and cranberry extracts for antioxidant coverage. There's also a small dose of stable vitamin C derivative and B-vitamins, which is a nice touch โ most toners this hydration-focused skip brightening support entirely. Texture-wise it's a light, slightly viscous toner with a soft pink tint (a EQQUALBERRY signature). It preps skin without any tackiness, which matters since it's meant to be layered under a serum and cream from the same line. Key ingredients: NAD+ (Nicotinamide Adenine Dinucleotide), Niacinamide, 12-Peptide Complex, Ceramide NP, Adenosine, Sodium Ascorbyl Phosphate (Vitamin C), Pomegranate & Berry Extract Blend Best used: AM + PM ๐ก Routine tip: Apply this toner with your hands rather than a cotton pad โ patting it in helps the peptide and NAD+ actives absorb instead of sitting on the surface where a pad could whisk them away. ย EQQUALBERRY NAD+ Peptide Boosting Serum โ 24.99 USD | 30ml Best for: Fine lines, loss of elasticity, and sagging along the jawline or cheeks This is the centerpiece of the line, and the one getting the most attention online for its hot-pink bottle and ingredient list. It pairs NAD+ with NMN (Nicotinamide Mononucleotide) โ both coenzymes involved in cellular energy production โ alongside a 14-peptide complex that includes Copper Tripeptide-1, a well-researched peptide known for supporting collagen, elastin, and overall tissue repair. What makes the formula feel complete rather than just trend-chasing is the supporting structure: five ceramide types plus vegan collagen for barrier reinforcement, and the same pomegranate-and-berry antioxidant blend found in the toner, so the line builds on itself rather than repeating actives without purpose. Squalane keeps the texture lightweight and fast-absorbing, which makes it easy to layer under a heavier moisturizer without feeling greasy. Reviewers consistently mention the same thing: a noticeably firmer, bouncier feel within the first few weeks, even before any visible line-softening shows up. That tracks with how peptides typically perform โ texture and firmness changes tend to show before deeper wrinkle changes. Key ingredients: NAD+, NMN (Nicotinamide Mononucleotide), 14-Peptide Complex, Copper Tripeptide-1, 5 Ceramide Types, Vegan Collagen, Squalane Best used: AM + PM ย EQQUALBERRY NAD+ Peptide Boosting Cream โ 25.99 USD | 50ml Best for: Sealing in the routine โ best for normal to dry skin that needs the firming actives locked in with a richer texture The cream closes out the NAD+ trio, and its job is less about introducing new actives and more about making sure everything underneath actually stays put. It carries NAD+ and a 13-peptide complex forward from the serum, plus niacinamide and the same pomegranate fruit juice for continued antioxidant support, all suspended in a richer base built around plant extracts (mushroom, jute, yam, and lotus root among them) that Korean formulas often use for their moisture-binding and skin-conditioning properties. The texture sits in that satisfying middle ground โ rich enough to feel like a proper moisturizer, but not so heavy that it pills under makeup. For drier skin types, it's substantial enough to be a one-step moisturizer; for normal or combination skin, it works well as a PM-only finishing step over the serum. Key ingredients: NAD+, 13-Peptide Complex, Niacinamide, Punica Granatum (Pomegranate) Fruit Juice, Phyto-Mucin Plant Extract Blend Best used: AM + PM ๐ก Pro tip: If you only have budget for one product to start with, the serum is the highest-concentration NAD+ step. Add the toner and cream once you know your skin tolerates the line well. The Supporting Product EQQUALBERRY Bakuchiol Plumping Serum โ 24.99 USD | 30ml Best for: Anyone who wants a retinol-alternative cell-turnover step alongside the NAD+ routine, especially sensitive or retinoid-cautious skin ๐ Note: This product does not contain NAD+ or NMN. It's included here as a cell-turnover companion, not a NAD+ delivery step. Bakuchiol works through a different mechanism โ gene-expression activity similar to retinol, without the irritation โ and its niacinamide, peptide, and ceramide base means it layers cleanly with the NAD+ line without any compatibility concerns or pH conflicts. Bakuchiol is a plant-derived compound from Psoralea corylifolia seeds, and it's earned its 'gentle retinol alternative' reputation honestly: clinical comparisons have found that 0.5% bakuchiol used twice daily performs comparably to 0.5% retinol for fine lines and photoaging, with meaningfully less irritation. This serum uses bakuchiol at 5,000ppm (0.5%), the concentration most of that research is based on. Where it earns its place in this routine specifically: the NAD+ line is built around coenzymes, peptides, and antioxidants, all of which support collagen indirectly. Bakuchiol adds a direct cell-turnover signal that the NAD+ products don't provide, which is the one gap in an otherwise complete routine. It shares the same niacinamide-and-ceramide base as the rest of the EQQUALBERRY lineup, so there's no risk of layering conflicts. Key ingredients: Bakuchiol (5,000ppm), Niacinamide, 13-Peptide Complex, 5 Ceramide Types, Adenosine, Allantoin Best used: PM, 3โ4x per week to start Your NAD+ Anti-Aging Routine at a Glance Step Product When Key Concern 1 NAD+ Peptide Boosting Toner AM + PM Hydration foundation + first NAD+ delivery 2 NAD+ Peptide Boosting Serum AM Firming, collagen signaling, elasticity 3 Bakuchiol Plumping Serum PM (3โ4x/week) Cell renewal, fine lines, pore tightening 4 NAD+ Peptide Boosting Cream AM + PM Barrier seal, moisture lock, long-term firmness Note: Bakuchiol and the NAD+ serum can both be used at night โ alternate them rather than layering both on the same evening while your skin adjusts. Why K-Beauty Gets to NAD+ Before Everyone Else NAD+ (and its precursor NMN) have been wellness-world buzzwords for a few years now, mostly tied to supplements and IV therapy aimed at cellular energy and longevity. Korean skincare's contribution has been figuring out how to put that same coenzyme science into a leave-on topical โ something the supplement industry, focused on oral and intravenous delivery, hasn't prioritized. That reflects a broader pattern in K-beauty formulation: take an ingredient with strong cellular-level research, then build the rest of the formula around making it work topically and pairing it with synergistic actives โ peptides for collagen signaling, ceramides for barrier support, antioxidant fruit extracts for environmental protection โ rather than launching a single-active product and calling it done. EQQUALBERRY's own brand philosophy (the name blends Equal, Quest, and Berry) leans into that same idea of balance over a single hero ingredient. For more on how K-beauty layers actives for compounding results, see our Peptides in K-Beauty guide and our PDRN skincare guide on the G-log, both of which cover other cellular-science ingredients K-beauty got to first. Final Thought NAD+ skincare is still new enough that the long-term topical research is thinner than it is for retinoids or peptides on their own โ but the early signs are promising, and the formulation logic here is sound: pair a cellular-energy coenzyme with proven peptides and a barrier-supporting base, then add a direct cell-turnover step alongside it. This four-product routine covers all of that without a single redundant step. Shop the full Nuriglow Anti-Aging Collection and find the NAD+ and bakuchiol formulas that fit your skin. All products are available at nuriglow.com! FAQ Q. What does NAD+ actually do for skin? A. NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme involved in cellular energy production and DNA repair. In skincare, it's used to support cell renewal and resilience, and is typically paired with peptides and ceramides to provide visible firming and barrier benefits alongside its cellular-level effects. Q. Is NAD+ skincare the same as NAD+ supplements or IV therapy? A. No. Supplements and IV NAD+ work systemically to support cellular energy throughout the body. Topical NAD+ skincare is formulated to act at the skin's surface and upper layers, and is better thought of as a topical antioxidant-and-peptide-support ingredient than a substitute for systemic NAD+ therapy. Q. Can I use NAD+ skincare with bakuchiol? A. Yes โ they work through different mechanisms and don't conflict. Many K-beauty routines layer a coenzyme/peptide step with a separate cell-turnover step like bakuchiol or retinol, similar to how niacinamide and Vitamin C are commonly paired. Q. Is NAD+ skincare safe for sensitive skin? A. Generally yes. NAD+, peptides, and ceramides are well-tolerated by most skin types. Bakuchiol is also considered gentler than retinol, though as with any new active, patch testing is recommended before full use. Q. How long does it take to see results from a NAD+ routine? A. Most people notice firmer, bouncier-feeling skin within 3 to 4 weeks. Visible changes to fine lines and elasticity typically take 8 to 12 weeks of consistent use, which is in line with how peptide-based anti-aging routines generally perform. Q. Do I need to use all four products, or can I start with just one? A. The serum carries the highest concentration of NAD+ and peptides, so it's the best single starting point. The toner and cream build on that foundation, and the bakuchiol serum is optional depending on whether you want a direct cell-turnover step alongside the coenzyme-based routine.

Panthenol in K-Beauty: The Quiet Overachiever Your Skin Has Been Waiting For
It doesnโt trend. It doesnโt glow in a serum bottle. But Korean skincare has used panthenol (vitamin B5) as a foundational ingredient for decades โ and once you understand why, youโll never underestimate it again. ย Introduction Thereโs a certain category of skincare ingredient that never gets a campaign behind it. No viral before-and-afters, no influencer launch events, no serum named after it (well, almost none). Panthenol โ the stable, cosmetic form of vitamin B5 โ is that ingredient. Itโs been a fixture in Korean skincare formulations for decades precisely because it works too well and too quietly to need a spotlight. K-beauty formulators donโt use panthenol as a headline ingredient because itโs already doing its job in every other formula: holding moisture, soothing inflammation, and quietly rebuilding the skin barrier while the named actives get all the attention. In last weekโs G-log, we looked at niacinamide and how K-beauty pairs it with unexpected co-ingredients. The NEEDLY Panthenol Water Gel Cream appeared as a supporting product โ and more than a few readers asked about it. So this week, weโre giving panthenol the standalone feature it deserves. If youโre dealing with sensitivity, dehydration, redness, or a barrier that just wonโt hold onto moisture, panthenol is very likely the piece youโre missing. This guide covers three panthenol-forward products at Nuriglow: a soothing prep toner, a clinically-formulated B5 serum, and the gel cream thatโs been a quiet favorite on the site for months. Three products, one ingredient philosophy, and a complete routine built around it. ย The Products: A Panthenol Routine Built for Real Skin ย ASIS-TOBE Forest Relaxing Facial Toner โ $9.90 USD | 200ml Best for: Sensitive, reactive, and combination skin; redness, irritation, barrier imbalance ย Every good skincare routine starts with a canvas thatโs calm enough to receive what comes next. ASIS-TOBEโs Forest Relaxing Facial Toner is designed for exactly that job โ and it earns its place as the first panthenol step in this routine. Itโs a lightweight, water-clear toner that works by addressing two things simultaneously: soothing active irritation and rebalancing the skinโs pH after cleansing so that every product you apply afterward absorbs properly. At $9.90 for 200ml, itโs one of the most accessible entry points into panthenol skincare on the site. The formula centers on Birch Sap (10,000 ppm), which functions as a deeply hydrating base rich in minerals and amino acids โ a calming first layer before any actives. Centella Asiatica and Madecassoside provide targeted soothing for redness and irritation, while panthenol strengthens the barrier and helps retain the moisture the toner delivers. Hinoki Leaf (Japanese cypress) and Bamboo extract add forest-derived botanicals with antioxidant and skin-calming properties. Itโs a simple, fragrance-free toner that does what a prep toner should: calm, hydrate, and open the skin to receive the next step. ย Key ingredients: Birch Sap (10,000 ppm), Centella Asiatica Extract, Madecassoside, Panthenol, Hinoki Leaf Extract, Sodium Hyaluronate pH: N/A (formulated for skin balance) Best used: AM + PM ย ย ๐ก Routine tip: Apply the Forest Relaxing Toner immediately after cleansing, while your face is still slightly damp. It absorbs in seconds and creates an ideal base for the B5 serum that follows. Can also be used with a cotton pad as a gentle wipe-down toner on congested days. ย DERCENT Pro Derma Hydrating Aquaporin B5 Serum โ $44.50 USD | 30ml Best for: All skin types; dry, dehydrated, sensitized, and post-procedure skin ย If panthenol is the hero ingredient of this routine, the DERCENT Pro Derma Hydrating Aquaporin B5 Serum is the delivery vehicle that takes it seriously. DERCENT is a Korean derma-skincare brand built on a single philosophy: replenish what skin is actually missing, using ingredients that mirror its own natural components. This serum is their flagship panthenol formula, and the approach is methodical. Rather than relying on panthenol alone, the formula uses a dual-action hydration system: panthenol (vitamin B5) for barrier repair and moisture binding, and Glyceryl Glucoside โ an aquaporin-activating active โ to literally improve the skinโs own water transport channels from within. Aquaporins are protein channels in skin cells that regulate the flow of water in and out of the cell. As skin ages or is stressed, aquaporin activity decreases, and hydration becomes less efficient even when youโre applying products diligently. Glyceryl Glucoside has been shown in clinical studies to upregulate aquaporin-3 expression โ meaning this serum doesnโt just add moisture, it improves your skinโs ability to move and retain moisture at the cellular level. Seven types of hyaluronic acid complete the formula, providing hydration at multiple molecular weights and depths. For anyone whose skin perpetually feels dry despite a consistent routine, this addresses the underlying mechanism rather than just the surface. ย Key ingredients: Panthenol (Vitamin B5), Glyceryl Glucoside (Aquaporin Activator), 7-Type Hyaluronic Acid Complex, Allantoin, Ceramide NP pH: 5.5 ยฑ 1.0 Best used: AM + PM ย ย ๐ก Pro tip: The DERCENT B5 Serum pairs exceptionally well with post-exfoliation or post-retinol skin. Panthenolโs wound-healing and barrier-repair properties make it one of the best calming actives to apply after any treatment that temporarily compromises the skin surface. Apply one to two pumps, press gently into the skin, and allow 60 seconds before the next step. ย NEEDLY Panthenol Water Gel Cream โ $24.00 USD | 50ml Best for: Oily, combination, and dehydrated skin; anyone wanting moisture without heaviness ย The NEEDLY Panthenol Water Gel Cream has been quietly earning its reputation on the G-log since it first appeared as a supporting mention in our niacinamide guide. Now it gets the full feature. NEEDLY is a Korean clinical skincare brand with a strong following in dermatology-adjacent K-beauty โ they formulate to a standard, not a trend โ and this gel cream is a perfect example of their approach. The goal is simple: deliver meaningful panthenol concentration in a texture light enough for oily skin, functional enough for dry skin, and pH-balanced precisely for daily use. The texture is the first thing you notice โ a water-burst gel that melts on contact and absorbs without any sticky residue or heavy film. Panthenol is the lead active, working to bind moisture in the epidermis, calm inflammation, and repair micro-damage in the barrier. Niacinamide in the supporting cast addresses tone and pore appearance, while Sodium Hyaluronate and Hyaluronic Acid hold surface hydration. The pH is balanced at 5.61 โ close to skinโs natural pH range โ which means it supports barrier health rather than disrupting it. For oily or combination skin types who have always found moisturizer to be the hardest step to commit to, this is the one that makes the case for not skipping it. ย Key ingredients: Panthenol (High Concentration), Niacinamide, Sodium Hyaluronate, Hyaluronic Acid, Allantoin, Betaine pH: 5.61 Best used: AM + PM ย ย Your Panthenol Routine at a Glance ย Step Product When Key Concern 1 ASIS-TOBE Forest Relaxing Facial Toner AM + PM pH reset + barrier prep 2 DERCENT Pro Derma Hydrating Aquaporin B5 Serum AM + PM Deep panthenol hydration + barrier repair 3 NEEDLY Panthenol Water Gel Cream AM + PM Moisture seal + shine-free finish ย Note: This three-step routine is intentionally streamlined. All three products are lightweight enough to layer quickly and work for AM and PM use. For maximum barrier repair, use the full sequence consistently for four weeks. Why K-Beauty Has Always Known About Panthenol ย Panthenol (D-Panthenol, or provitamin B5) converts to pantothenic acid โ vitamin B5 โ in the skin. That conversion triggers a cascade of effects: increased moisture retention in the stratum corneum, accelerated wound healing and barrier repair, reduction in transepidermal water loss (TEWL), and anti-inflammatory activity that calms redness and irritation. Itโs one of the few cosmetic ingredients that has both a humectant effect (drawing moisture in) and an emollient effect (creating a film that keeps it from escaping), making it unusually complete as a hydration active. Korean formulators understood this profile early. Panthenol appears in Korean cosmetic formulations at meaningful concentrations โ often listed in the top five to ten ingredients โ whereas in many Western formulations it appears much further down the list as a texture modifier or label claim. The distinction matters. At low concentrations, panthenol provides cosmetic feel. At meaningful concentrations, it changes how the barrier functions. This is the difference between panthenol as a supporting note and panthenol as a working ingredient, and K-beauty has consistently leaned toward the latter. The three products in this guide all use panthenol as a working ingredient: the ASIS-TOBE toner primes the barrier before any serum is applied; the DERCENT B5 serum delivers a clinically significant concentration alongside the aquaporin-activating glyceryl glucoside; and the NEEDLY gel cream seals the work in with a formula calibrated to the skinโs natural pH. Used together, they build the kind of barrier resilience that doesnโt require you to keep adding more to your routine. For a deeper look at how layered hydration works in K-beauty, our glass skin guide walks through the full framework. ย ย Final Thought ย Panthenol wonโt give you a before-and-after moment. What it gives you instead is skin that gradually stops reacting, stops feeling tight after cleansing, and starts holding onto moisture the way itโs supposed to. Itโs the kind of improvement that sneaks up on you โ two weeks in, you realize your skin just looks calmer. Thatโs panthenol doing its job. Start with the ASIS-TOBE toner as your daily prep layer. Add the DERCENT B5 serum if your skin runs dry or is dealing with any kind of barrier disruption. Finish with the NEEDLY gel cream for a clean, shine-free seal. Itโs a routine built for consistency rather than complexity โ which is exactly the kind of routine K-beauty does best. ย Shop the more products and find the panthenol routine that works for your skin. All products are available at nuriglow.com! ย ย FAQ ย Q. What exactly is panthenol and how is it different from vitamin B5? A. Panthenol is the stable, cosmetic form of vitamin B5 (pantothenic acid). When applied to skin, D-Panthenol โ the form used in skincare โ converts enzymatically into pantothenic acid, which is then used by the skin cells for barrier repair, moisture regulation, and cellular regeneration. The two terms are often used interchangeably in K-beauty marketing. When a product claims โvitamin B5โ in its key ingredients, it almost always contains D-Panthenol. Q. Is panthenol safe for sensitive and reactive skin? A. Yes โ panthenol is one of the most universally well-tolerated skincare ingredients. It has no known irritation potential and is commonly recommended by dermatologists for sensitive, post-procedure, and eczema-prone skin. Unlike many actives that produce visible results by temporarily irritating or disrupting the skin surface, panthenol works by repairing and reinforcing. Itโs a genuine choice for anyone who reacts to most actives. All three products in this guide are fragrance-free and formulated for sensitive skin compatibility. Q. Can I use panthenol with other actives like retinol, AHAs, or niacinamide? A. Not only can you โ you should. Panthenol is one of the best pairing ingredients for any active that temporarily compromises the skin barrier. When using retinol or chemical exfoliants, the skinโs barrier is stressed and TEWL increases. Panthenol applied after these actives accelerates barrier recovery, reduces post-active redness, and prevents the dehydration that often causes people to give up on exfoliation altogether. Niacinamide and panthenol are especially complementary โ niacinamide handles tone and pore control while panthenol handles moisture and barrier function. Q. How long does it take to see results from a panthenol routine? A. Panthenolโs barrier-strengthening effects are measurable within 24 to 48 hours of application โ which is why itโs used in wound-healing and post-procedure protocols. For general skincare, most people notice that skin feels less tight and reactive within the first week. More significant improvements in overall hydration level, redness, and barrier resilience typically appear after two to four weeks of consistent use. Unlike brightening actives, panthenolโs benefits are cumulative and structural rather than cosmetic โ the skin genuinely functions better over time. Q. Whatโs the difference between panthenol in a serum vs. a moisturizer? A. In a serum (like the DERCENT B5 Serum), panthenol is delivered at higher concentrations and penetrates more deeply into the epidermis, where it does structural barrier work. In a moisturizer (like the NEEDLY Panthenol Water Gel Cream), panthenol helps lock in the hydration from earlier layers and provides a longer-lasting seal on the surface. For the most complete effect, using both โ serum first, cream after โ delivers panthenol at multiple skin depths, which is exactly the layering approach that K-beauty is built around. Q. Why does the DERCENT serum mention aquaporins? What does that mean for my skin? A. Aquaporins are tiny protein channels in your skin cells that regulate the movement of water in and out of the cell. Think of them as microscopic hydration gates. When aquaporin activity is high, water moves efficiently through the skinโs layers and hydration is more effective โ which is why well-hydrated skin looks plump and even-toned. As skin ages, or is stressed by UV, pollution, or over-cleansing, aquaporin expression decreases, and even heavy moisturizer application stops translating into lasting hydration. The Glyceryl Glucoside in the DERCENT B5 Serum has been shown to upregulate Aquaporin-3, improving the skinโs own water transport efficiency from the cellular level up. ย ย References ย Images: Getty Images B6ud3X0CA, Unsplash ย Written by Sena Lee for the G-Log โ Nuriglowโs K-beauty edit for real skin.
Niacinamide in K-Beauty: The One Ingredient That Brightens, Tightens, and Balances All at Once
If your skin needs to look better but you can only add one thing โ Korean formulators have long had an answer, and it starts with niacinamide. ย Introduction Niacinamide has had a quiet glow-up of its own. Once considered a supporting ingredient โ the kind that showed up third or fourth on an ingredient list without getting much credit โ it's now one of the most-searched skincare actives in the world. But here's what Western brands have been slower to figure out: niacinamide isn't a one-trick brightener. In Korean skincare, it's used as a genuine multitasker to refine pores, regulate sebum, calm inflammation, fade dark spots, and strengthen the skin's moisture barrier, often all in the same formula. Korean dermatologists and formulators have been studying and utilizing niacinamide for decades, and the resulting products reflect a depth of formulation know-how that's hard to find elsewhere. What makes K-beauty niacinamide products distinctive isn't just the concentration โ it's the pairing. Korean chemists are unusually skilled at layering niacinamide alongside synergistic ingredients: fermented ceramides, madecassoside, ginseng berry, pineapple enzymes, glutathione. The results are formulas that deliver noticeably more comprehensive skin improvements than a single-active product ever could. If you've been using niacinamide in some form and felt underwhelmed, chances are it's because the formula surrounding it wasn't doing enough. The four products below change that. This week's G-log covers four niacinamide-forward K-beauty picks available right now at Nuriglow โ each chosen for a distinct formulation approach and skin concern angle. Whether your goal is fading post-breakout marks, strengthening a compromised barrier, or building that steady glass-skin radiance, there's a pick here built specifically for it. ๐ก Routine tip: Niacinamide is one of the most versatile actives in skincare โ it plays well with acids, retinoids, vitamin C, and peptides. No need to avoid layering; apply thinner textures first and let each layer absorb before the next. ย Four Niacinamide Picks Worth Knowing Biodance Radiant Vita Niacinamide Serumย โย $21.90 USD | 30ml / 1.01 fl. oz. Best for: All skin types; especially dull, combination, or uneven skin looking for a daily brightening serum that doubles as a preventative treatment Biodance built this serum on a quietly brilliant insight: niacinamide works better when it has the right co-stars. The Radiant Vita Niacinamide Serum pairs niacinamide with pineapple water โ a natural source of vitamin C and mild exfoliating enzymes โ and glutathione, the antioxidant powerhouse that inhibits melanin production at the enzyme level. This trio works on multiple levels: niacinamide blocks melanin transfer to skin cells, glutathione interrupts the synthesis of dark pigment upstream, and pineapple water accelerates surface-level cell turnover. The result is a serum that doesn't just address existing dullness but actively prevents new spots from forming. At pH 6.0, it's calibrated for comfortable daily use without stinging or stripping, and the texture is lightweight enough to wear under SPF without pilling. What makes it a genuine staple is its consistency: used every morning, the skin starts reading as clearer, more even-toned, and noticeably more luminous within two to three weeks. Among the most effective entry points into niacinamide skincare at this price point โ and the kind of formula that makes the rest of your routine work harder. Key ingredients: Niacinamide, Pineapple Water (Ananas Sativus Fruit Water), Glutathione, Biosaccharide Gum-1, Coptis Japonica Root Extract pH: 6.00 ยฑ1.00 Best used: AM + PM Certifications: Vegan, Cruelty-Free, Non-Comedogenic, Fragrance-Free, Clinically Tested ๐ก Pro tip: Apply to slightly damp skin right after cleansing for faster absorption. Follow immediately with a moisturizer to seal in the actives. ย SKINRx LAB MadeCera Creamย โย $34.00 USD | 50ml / 1.69 fl. oz. Best for: Sensitive, acne-prone, or barrier-compromised skin that needs brightening without irritation; anyone who wants niacinamide in a genuinely multitasking moisturizer The MadeCera Cream has quietly become one of K-beauty's most reliable cult formulas โ the kind that keeps showing up in routines across skin types because it solves several problems without creating new ones. The core of the formula is a triple partnership: niacinamide for brightening and pore refinement, madecassoside (the bioactive compound from centella asiatica) for calming inflammation and reducing acne-related redness, and fermented Ceramide NP at 10,000ppm for barrier reinforcement and moisture retention. Adenosine rounds things out with clinically validated anti-aging and skin-smoothing activity. What makes MadeCera stand apart is the clinical testing behind it: SKINRx LAB has published two-week data showing 103% improvement in skin moisturization, and separate testing showed 46% reduction in closed comedones and 36% reduction in open comedones after four weeks. For skin that's both sensitive and prone to breakouts โ a frustrating combination โ this is among the most thoughtfully formulated moisturizers in the K-beauty market. Despite the rich ingredient profile, the texture absorbs cleanly and doesn't pill under SPF or makeup. This is the one to reach for when the skin barrier needs rebuilding without sacrificing the brightening work. Key ingredients: Niacinamide, Ceramide NP (10,000ppm), Madecassoside, Asiaticoside, Adenosine, Panthenol, Squalane Best used: AM + PM Certifications: Paraben-Free, Mineral Oil-Free, Surfactant-Free ๐ก Routine tip: Layer the Biodance Niacinamide Serum underneath the MadeCera Cream for a concentrated brightening-plus-barrier routine โ the serum delivers the actives, the cream seals them in and adds ceramide-level barrier support on top. ย CLIV Ginseng Berry Premium Creamย โย $27.99 USD | 50ml / 1.69 fl. oz. Best for: Dull, tired, or maturing skin that needs brightening and firming from one moisturizer; especially suited for those in their late 20s to 40s CLIV takes a different approach to niacinamide โ pairing it with one of Korean skincare's most storied botanical heroes: ginseng. The Ginseng Berry Premium Cream uses fermented Ginseng Berry Filtrate and Ginseng Callus Extract as its base, delivering the antioxidant depth and skin-revitalizing effect that has made ginseng a fixture in Korean clinics and pharmacies for centuries. Ginseng saponins support barrier integrity and microcirculation, while the fermentation process increases bioavailability โ meaning more of the actives reach skin cells rather than sitting on the surface. Niacinamide serves as the brightening and tone-evening anchor, working alongside ginseng's naturally radiance-boosting properties to address both the cause (melanin production, oxidative stress) and the appearance (dullness, uneven texture) of skin that's lost some of its natural luminosity. The texture is richer than a typical brightening serum but absorbs cleanly, finishing luminous rather than heavy. For anyone who wants niacinamide's benefits in a format that also works as a genuine anti-aging moisturizer โ the kind you reach for every morning because your skin just looks better โ this is the one. Key ingredients: Niacinamide, Fermented Ginseng Berry Filtrate, Ginseng Callus Extract, Ginseng Berry Saponin Best used: AM + PM Certifications: Cruelty-Free ๐ Also worth knowing: NEEDLY Panthenol Water Gel Cream โ $24.00 USD | 50mlย Not a niacinamide formula, but one of its best partners. Panthenol (vitamin B5) and niacinamide are closely related members of the B-vitamin family, and their effects are complementary rather than overlapping. While niacinamide handles tone and pore control, panthenol rebuilds the skin barrier from within โ healing micro-damage, locking in moisture, and creating the kind of well-hydrated, intact surface that lets niacinamide work more effectively. The NEEDLY gel cream is lightweight, fragrance-free, and pH-balanced at 5.61, making it ideal for oily or combination skin that wants moisture without weight. Use it as your moisturizer on reactive days, or layer it under the CLIV Ginseng Cream in drier months. (A dedicated guide to panthenol in K-beauty skincare is coming soon to the G-log.) ย Why Korean Skincare Gets More from Niacinamide Niacinamide (vitamin B3) has been well-understood by Korean dermatology since the late 1990s โ long before it became a Western skincare buzzword. That head start shows in the formulas. Korean chemists have had decades to experiment with optimal concentrations, pairing strategies, and delivery systems, and the resulting products use niacinamide not as a single hero but as a conductor โ coordinating a broader cast of ingredients toward a shared goal. What makes niacinamide uniquely valuable is the breadth of its function. It inhibits the transfer of melanosomes (pigment packets) from melanocyte cells to skin cells โ the mechanism behind dark spot formation. It regulates sebaceous activity, meaning it can meaningfully reduce pore appearance in oily skin over time. It reinforces the ceramide and free fatty acid content of the stratum corneum, translating to a stronger moisture barrier and less transepidermal water loss. And it has well-documented anti-inflammatory properties, making it one of the few brightening actives genuinely suitable for sensitive skin. Korean formulators have consistently been ahead of the curve in pairing niacinamide with ingredients that address the same problems via different mechanisms. Madecassoside reduces the inflammation that drives post-breakout pigmentation. Glutathione inhibits tyrosinase, the enzyme that produces melanin at source. Ginseng saponins reduce oxidative stress that accelerates skin aging and dullness. Ceramides repair the barrier that, when compromised, makes all other actives less effective. The result is a category of products that doesn't just target one step in the pigmentation or aging pathway โ it addresses all of them simultaneously. That's the compounding effect Western single-active formulas rarely achieve. For more on how K-beauty layers actives for broader results, see our Peptides in K-Beauty guide on the G-log. Final Thought Niacinamide is the rare active that genuinely does what the packaging says โ but only when the formula around it is doing its job. The four picks in this guide represent K-beauty at its most ingredient-intelligent: a brightening serum that pairs niacinamide with glutathione and pineapple enzymes for multi-pathway pigmentation control; a cult barrier cream that combines niacinamide with fermented ceramides and madecassoside for skin that's clear, calm, and well-defended; a ginseng-powered moisturizer for those who want firming and anti-aging alongside the even-tone effect; and a panthenol companion for days when the barrier needs rebuilding. It's a complete, adaptable niacinamide toolkit โ and it's all under $100. Shop the full Nuriglow Brightening Collection and find the niacinamide formula that fits your skin. All products are available at nuriglow.com! ย FAQ Q. What does niacinamide actually do for skin? A. Niacinamide (vitamin B3) performs multiple functions simultaneously: it blocks the transfer of dark pigment to skin cells (reducing dark spots and uneven tone), regulates sebum to visibly minimize pores over time, strengthens the skin barrier by supporting ceramide production, and calms inflammation. K-beauty uses it as a true multitasker โ not just a brightener. Q. What percentage of niacinamide should I look for in a serum or cream? A. Concentrations between 2% and 10% are effective and well-tolerated by most skin types. K-beauty products typically work in the 4โ5% range as a sweet spot โ potent enough to deliver results without irritation. Higher concentrations don't necessarily produce better outcomes and can cause flushing in sensitive individuals. Q. What's the difference between niacinamide for brightening vs. niacinamide for pores? A. It's the same ingredient โ niacinamide addresses both via different mechanisms. For pores: it regulates sebum production over time, reducing the excess oil that makes pores appear larger. For brightening: it interrupts the transfer of melanin to skin cells, fading existing dark spots and preventing new ones. Both effects require consistent daily use for 4โ8 weeks before they're fully visible. Q. Can I use niacinamide with vitamin C at the same time? A. Yes โ this combination is safe in modern formulations. An older concern about the two forming a yellow byproduct was based on outdated research using unstable vitamin C forms at high temperatures. Stable vitamin C derivatives used in current K-beauty formulas have no such interaction. Apply vitamin C first in your AM routine, let it absorb, then layer niacinamide on top. Q. Is niacinamide safe for sensitive or acne-prone skin? A. Yes, and it's one of the better actives for both concerns. Its anti-inflammatory properties often reduce redness rather than aggravating it, and its sebum-regulating effect supports acne-prone skin over time. For very reactive skin, the SKINRx LAB MadeCera Cream โ with its madecassoside-and-ceramide base โ is a particularly well-suited entry point, as the calming ingredients offset any adjustment period. Q. How long does it take to see results from a niacinamide product? A. Improved skin texture and reduced oiliness typically become noticeable within 2โ4 weeks. Visible brightening and dark spot fading requires 4โ8 weeks of consistent daily use. The most significant results โ substantially more even tone and smaller-looking pores โ build over 3 months. Consistency matters more than concentration. ย References Images: Ruliff Andrean S3vNKDwUK4w, Unsplash ย Written by Sena Lee for the G-Log โ Nuriglow's K-beauty edit for real skin.
