1. What is PDRN?
PDRN (Polydeoxyribonucleotide) is a DNA-derived skin-repair ingredient known for stimulating skin regeneration, reducing inflammation, and accelerating the recovery of damaged skin. Originally sourced from salmon DNA, it's now also available in vegan forms derived from plants and microorganisms, making it a key ingredient in both functional and clean beauty skincare.
2. What Does PDRN Do for Your Skin?
- ✅ Promotes skin cell regeneration
- ✅ Calms inflammation and irritation
- ✅ Strengthens the skin barrier
- ✅ Boosts collagen production for firmer skin
PDRN activates skin recovery through signaling pathways that stimulate growth factors—like fibroblast growth factor (FGF)—and boost DNA synthesis in skin cells. This leads to faster tissue repair, reduced inflammation, and stronger skin resilience over time.
3. How Can I Know That a Product Contains PDRN?
In skincare, you’ll often see PDRN under the following names:
- Hydrolyzed DNA – Broken-down DNA molecules that absorb easily into skin
- Sodium DNA – A stable salt form of PDRN for enhanced efficacy
💡 What’s the Difference?
Hydrolyzed DNA is your skin’s first responder. It sinks into the skin quickly because of its small fragments—making it ideal for lightweight, daily-use serums that calm and hydrate.
Sodium DNA is the long-term builder. As a more stable form, it works deeper and longer—perfect for intensive recovery and anti-aging treatments.
Use Hydrolyzed DNA when targeting instant soothing and absorption.
Use Sodium DNA for rebuilding strength and elasticity over time.
4. Vegan vs. Salmon PDRN — What's the Difference?
| Feature | Salmon PDRN | Vegan PDRN |
|---|---|---|
| Source | Salmon testes | Plants or microbial fermentation, etc |
| Animal-Free? | ❌ | ✅ |
| Allergy Risk | Higher (marine protein) | Low (sensitive skin-friendly) |
Salmon PDRN is clinically backed for wound healing, anti-aging, and post-procedure care. It is also known for its ability to be extracted at high concentrations, allowing for maximum potency in ampoules and intensive treatments.
Vegan PDRN is better suited for those seeking cruelty-free, low-irritant solutions, and is rising in popularity in clean beauty.
5. What Product Should I Try? (Best Picks by Skin Type)
| Skin Type | Dry / Mature Skin | Sensitive / Irritated Skin | Anti-Aging / All Skin Types |
|---|---|---|---|
| Product |
![]() Dr.ROSA PDRN Ampoule |
![]() Maybena Vegan PDRN Serum |
![]() Medicube PDRN Ampoule |
| Main Feature | Vegan PDRN from seaweed | Vegan PDRN from microorganisms | PDRN + Peptides dual repair system |
| Key Benefit | Firming, lifting, and barrier support | Daily soothing and barrier recovery | Elasticity + wrinkle care |
If you’re seeking a skincare ingredient that goes beyond surface hydration and actively rebuilds damaged skin, PDRN is worth exploring. Vegan PDRN, in particular, answers the rising demand for effective, ethical, and science-based skincare, especially among ingredient-conscious shoppers. Whether your skin needs to calm down, bounce back, or glow up — PDRN might just be your next holy grail.
