PDRN Skincare: What It Is, What It Does, and Why I Swear by Rejuran
My favorite PDRN ampuole :D
- PDRN (polydeoxyribonucleotide) is a regenerative, barrier-supportive ingredient often sourced from salmon DNA.
- Best for recovery: post-retinoid, post-acid, post-procedure, irritated or sensitized skin.
- Not a “peel” or “instant glow” active; think calm + resilience over time.
- I repurchased Rejuran and it’s now in my ride-or-die product list.
If you’ve been seeing PDRN skincare everywhere ie ampoules, serums, post-procedure routines- you’re not imagining it. PDRN is officially having a moment. And unlike many viral ingredients, this one has real roots in regenerative medicine.
As a dermatologist, I’m cautious when a “new” ingredient trends overnight. PDRN is different. I’ve now repurchased Rejuran, I use it regularly, and it has officially earned a spot on my ride-or-die list—especially on recovery nights and when my skin barrier needs real support.
What is PDRN
PDRN stands for polydeoxyribonucleotide which is a DNA-derived compound studied in contexts related to tissue repair and healing. In skincare, it’s often nicknamed “salmon DNA” because it’s commonly sourced from salmon-derived DNA.
Practically, PDRN functions more like a recovery and resilience ingredient than a classic “active” like retinoids or acids. It’s designed to support the skin’s natural restoration processes, especially when your barrier is stressed.
What does PDRN do for the skin
Think of PDRN as a skin quality ingredient. It’s not about peeling or stripping. It’s about helping skin behave better.
- Supports skin barrier repair and overall resilience
- Helps calm visible irritation from retinoids, acids, winter dryness, or overdoing it
- Plays well with active routines because it’s generally non-exfoliating
- Pairs nicely post-procedure as a recovery-focused step (depending on your provider’s instructions)
What PDRN is not
- Not a chemical exfoliant
- Not a substitute for acne treatments like retinoids or benzoyl peroxide
- Not an overnight miracle (if you want “instant,” you’ll be disappointed)
PDRN vs growth factors vs exosomes
These get lumped together online, but they’re not interchangeable. Here’s the simplest useful framing:
| Category | What it is | Best use-case vibe |
|---|---|---|
| PDRN | DNA derived regenerative support ingredient | Barrier recovery, calm, resilience, post-active “repair” routines |
| Growth factors | Signaling proteins used to support skin renewal pathways | Skin quality, texture support, post-procedure routines (product-dependent) |
| Exosomes | Cell derived messengers (topical data varies) | Often positioned for advanced rejuvenation; evaluate claims carefully |
Why PDRN skincare is trending right now
- Barrier repair is finally mainstream (and it should be! Irritated skin doesn’t clear acne well)
- More people are doing in office treatments and want smarter recovery routines
- K beauty + medical aesthetics overlap has pushed PDRN into consumer skincare
- It layers beautifully with retinoids and acids without adding more exfoliation
My experience with Rejuran (yes, I repurchased)
I don’t repurchase trendy products lightly. But Rejuran’s PDRN ampoule has been consistently good to my skin, especially during weeks when I’m using retinoids more frequently or when my barrier feels finicky.
I’ve repurchased Rejuran, and it’s now officially a ride-or-die for me in the “repair and resilience” category: elegant texture, layers easily, and my skin tends to feel noticeably calmer the next day.
How to use PDRN in a routine
My favorite way
- Gentle cleanse (no scrubs, no drama).
- Apply retinoid to dry skin- Altreno, I'm looking at you, baby.
- Apply PDRN ampoule to slightly damp skin.
- Wait 30–60 seconds.
- Seal with a thick, barrier-supportive moisturizer.
When I reach for it most
- After a week of heavy retinoid use
- After acids or when skin feels “tight” or reactive
- Winter dryness flares
- As a dedicated weekly “repair night” step
Who should consider PDRN skincare
PDRN is especially useful if you:
- Use tretinoin or other retinoids
- Have acne-prone but sensitive skin
- Get in-office treatments and want a calmer recovery routine
- Want long-term skin quality and barrier stability
Who might not need it
If your skin is very resilient, you don’t use actives, and you rarely experience irritation or dryness, PDRN may be a “nice to have,” not a must.

FAQs about PDRN skincare
What is PDRN in skincare?
PDRN (polydeoxyribonucleotide) is a DNA-derived ingredient commonly used in “regenerative” skincare. It’s often sourced from salmon-derived DNA and is typically positioned for barrier support and recovery rather than exfoliation.
Is PDRN the same as salmon sperm facial treatments?
People use those phrases interchangeably online, but they can refer to different things depending on the product or treatment. Many topical PDRN products are inspired by the same concept,regenerative support, but are not the same as in-office procedures or injectables.
Can acne-prone skin use PDRN?
Often yes, especially if your acne routine includes retinoids or acids and you experience irritation or barrier disruption. PDRN is usually used as a calming, supportive step rather than an acne “treatment active.”
How do you layer a PDRN ampoule?
Cleanse, apply PDRN to slightly damp skin (I like to do it after a retinoid), let it absorb, then seal with a moisturizer. Keep the routine simple on PDRN nights.
How often should I use PDRN?
Many people do well using it 1–3 nights per week, especially on “repair nights.” If you’re sensitive, start low and slow and monitor for any irritation.
