PDRN (Polydeoxyribonucleotide)
What it is and how it works:
PDRN – short for polydeoxyribonucleotide – is a cellular activator composed of DNA fragments, traditionally extracted from salmon DNA (which closely mirrors human DNA) or derived from specific plant sources. Rather than sitting on the surface like traditional ingredients, PDRN works on a cellular level by binding to skin receptors to kick-start tissue repair, trigger massive collagen synthesis, and radically accelerate the skin's natural healing process.
PDRN is best suited for: Ageing, dull, compromised, or post-procedure skin looking for deep structural rejuvenation.
Skin types/concerns that PDRN helps with: Loss of elasticity, fine lines, acne scarring, persistent redness, dehydration, and a damaged skin barrier.
Pairs well with: Hyaluronic acid, niacinamide, peptides, vitamin C, and exosomes.
Doesn’t pair well with: There are no major ingredient conflicts! However, be cautious when layering it in the exact same application as high-strength exfoliating acids (AHAs/BHAs) to avoid over-stimulating sensitive skin.
FAQs
How do I use PDRN?
Because PDRN is incredibly gentle and restorative, it can be used daily, both morning and night.
Apply your PDRN serum or essence immediately after cleansing and toning, then follow with your usual moisturiser to lock in the benefits.
Can I use PDRN with retinol?
Yes, they’re an excellent pairing. While retinol aggressively drives cell turnover and can cause irritation, PDRN works from within to repair, soothe and build up the skin barrier, effectively buffering the unwanted side effects of retinoid use.
Is PDRN meant to sting or tingle?
No. PDRN itself is completely non-irritating and anti-inflammatory. If you experience a tingling sensation, it’s likely due to other active ingredients in the specific formulation (such as microneedles or exfoliating spicules often found in K-beauty booster serums).
Does PDRN help acne?
It won’t clear active, bacteria-driven acne breakouts, but it is highly effective at healing the skin post-breakout. It actively speeds up the fading of post-inflammatory hyperpigmentation (acne marks) and aids in flattening depressed acne scars.
Is it okay to use hyaluronic acid with PDRN?
Absolutely. PDRN actually encourages the skin to produce its own hyaluronic acid from within. Layering the two together provides a massive double-hit of deep, bouncy hydration.
Where does PDRN come from?
Most clinical and cosmetic PDRN is sustainably sourced from salmon DNA. However, plant-derived alternatives (like wild ginseng or red bean PDRN) are increasingly popular for those seeking vegan-friendly options.
Can you use PDRN every day?
Yes. Unlike acids or retinols that require a tolerance build-up, PDRN is an intensely hydrating repair agent that can be used twice daily right from the start.
Can you use PDRN when pregnant or breastfeeding?
Yes. PDRN is considered safe for use during pregnancy and breastfeeding, providing a brilliant, low-risk option for managing the loss of elasticity and hormonal skin changes.
Does PDRN help psoriasis or eczema?
Because of its clinically proven wound-healing and anti-inflammatory properties, it can help calm redness and repair a broken skin barrier.
Note: We recommend speaking to a professional before using PDRN on any medical-grade skin conditions.
Does PDRN hydrate skin?
Yes, immensely. It functions differently to a topical moisturiser – by boosting the skin's internal glycosaminoglycan production, it increases your skin's natural capacity to hold onto water.
What’s the difference between PDRN and Polynucleotides (PN)?
It comes down to molecular weight. PDRN consists of shorter DNA fragments, meaning it penetrates the skin deeply and rapidly to target cellular repair. Polynucleotides have a larger molecular weight, forming a supportive matrix on the skin's surface to enhance elasticity and hydration over a broader area.
Any tips for using PDRN?
● The K-beauty glow hack: Gently pat (don't rub) PDRN products into the skin to enhance
absorption and boost that instant ‘glass skin’ radiance.
● Post-treatment recovery: Keep a PDRN serum or sheet mask on-hand to fast-track your
recovery after professional clinical treatments like microneedling or lasers.
