Korean skincare continues to set the pace when it comes to ingredient innovation. Snail mucin, tranexamic acid and Centella asiatica are just a few examples that now sit firmly within our routines. The latest to enter the conversation is PDRN, an ingredient rooted in Korean aesthetic medicine that’s being touted as skincare’s next barrier-boosting hero.
PDRN may feel fresh to our shop shelves, but it’s been used in Korean clinics for over a decade. “Korean skincare and aesthetics are estimated to be around 10 to 12 years ahead of us in terms of innovation,” says Dr Christine Hall, K-beauty expert and GP at TakTouk Clinic. “They really are pioneering the way in beauty.”
One of the earliest injectable PDRN treatments, Rejuran, launched in Korea back in 2014 – long before the ingredient began appearing in topical skincare here. “Ingredients like this are often used, tested and refined in Korea for years before they reach the UK,” Dr Hall explains. “By the time we see them, there’s already a strong track record behind them.”
At the heart of K-beauty is an emphasis on protecting and strengthening the skin barrier, rather than overwhelming it – and PDRN is used to support exactly that. According to Dr Hall, it helps to hydrate the skin, calm redness and reduce inflammation, which explains its popularity in formulas designed for sensitive or compromised skin.
While injectable polynucleotides remain the gold standard in clinic, topical PDRN offers a more accessible way to introduce the ingredient at home. As Dr Jinah Yoo, consultant dermatologist at Dr Jinah Yoo Dermatology & Anti-Ageing notes, “topical formulas are best viewed as a supportive step, particularly when the skin barrier needs calming or recovery.”
Ahead, we round up the best PDRN serums and creams that deserve a spot on your beauty shelf…
If glass-smooth skin is the goal, Medicube’s PDRN Pink Peptide Serum is a good place to start. Formulated with a 10,000ppm concentration of PDRN, alongside niacinamide and the brand’s five-peptide complex, the silky pink serum feels immediately hydrating and calming on application. With regular use, it helps support the skin barrier, fade pigmentation and boost glow. Tick, tick, tick!
This is not a heavy, occlusive moisturiser. Instead, Dr.Althea’s PDRN Reju 5000 Cream has a lightweight, fast-absorbing texture that leaves skin feeling cushioned and comfortable. Best suited to skin prone to dryness and sensitivity, the formulation pairs PDRN with Centella asiatica, panthenol and multi-weight hyaluronic acid to support the skin barrier and maintain hydration.
This hydrating serum from Anua feels barely there on the skin. The water-like texture absorbs quickly, delivering hydration without any residue or shine. PDRN is combined with hyaluronic acid and hydrolysed collagen, while capsule technology helps release moisture gradually throughout the day. Ideal for dry or dehydrated skin, expect a refreshed, more radiant complexion after just one use.
If brightening is the aim of the game, this best-selling ampoule (aka a concentrated, serum-style step) from Genabelle is worth knowing about. Developed with sensitive skin in mind, the gentle formula combines 5,000ppm of PDRN with encapsulated vitamins and a mix of hydrators to support the skin barrier while delivering good glow. Apply morning or night and gently roll the capsules into the skin.
Alongside vegan Rose PDRN and peptides, this serum contains a low-dose 0.1% retinal to help refine texture and support firmness without overwhelming the skin. It reflects a wider K-beauty approach to actives, favouring encapsulated or lower-strength forms to minimise irritation. Best used in the evening, it suits skin looking to gently improve tone, texture and overall skin quality over time.
This is one of the richer options in the line-up, making it well suited to skin that’s in need of extra comfort. The nourishing cream is formulated with a high level of purified, pharmaceutical-grade PDRN, alongside niacinamide, panthenol and hyaluronic acid, to support hydration and barrier repair. If you’re dealing with post-treatment dryness or a weakened skin barrier, this is the perfect pick.
If fish-derived PDRN isn’t for you, this ginseng-based vegan option is worth considering. The texture sits somewhere between an essence and a serum, with a milky feel that sinks in speedily and leaves skin feeling hydrated but not coated. Panthenol, ceramides and squalane help reinforce the barrier, while the fragrance-free formula makes it a good choice for sensitive skin.
What does PDRN do for the skin?
PDRN is best understood as a barrier-supporting ingredient, valued for its calming and restorative effects rather than dramatic results. While research into its exact mechanisms is still evolving, dermatologists tend to view topical PDRN as a recovery step – something that helps skin settle, rebalance and strengthen over time.
“PDRN is a DNA-derived compound studied for tissue repair,” explains Dr Yoo. “With topical use, patients are more likely to notice skin that feels calmer, better hydrated and less reactive, with a stronger-looking barrier after several weeks of consistent use.”
In clinic, Dr Yoo finds it most useful for skin that needs support – for instance, post-procedure. Used as a serum or moisturiser step, particularly in the evening, it works well alongside other barrier-focused ingredients such as ceramides, hyaluronic acid, panthenol and niacinamide.
Can PDRN replace polynucleotide treatments?
In short, no – and the experts are keen to be clear on that distinction. “The strongest evidence is for injectable polynucleotides,” says Dr Yoo. While topical PDRN is promising, penetration remains a key limitation, meaning its effects are supportive rather than comparable to in-clinic treatments.
Topical products contain PDRN (polydeoxyribonucleotide), while injectable treatments use PN (polynucleotides). The two are closely related, but delivery makes a significant difference. When injected, polynucleotides can stimulate fibroblasts (the cells responsible for collagen production), leading to measurable changes in skin thickness, texture and repair. Injectables were originally studied for wound healing, including burns and diabetic ulcers, which is why their regenerative potential is so well documented.
By contrast, PDRN is a large molecule – making it unlikely to penetrate deeply enough through intact skin to stimulate collagen in the same way. That doesn’t mean topical PDRN has no value, just that its role is different. As Dr Hall explains, “skincare ingredients don’t need to be classed as medical devices, so they aren’t held to the same evidential standards. Instead, dermatologists consider biological plausibility and real-world use.”
A helpful comparison is collagen in skincare – while topical collagen doesn’t increase collagen levels in the skin, it still acts as an effective humectant, improving hydration and skin comfort. In the same way, topical PDRN may not trigger deep regeneration, but it can be very effective at calming, soothing and supporting skin. Dr Yoo also notes that encapsulation or lipid-based delivery systems may improve performance, and that PDRN can be particularly useful post-procedure, when the skin barrier is temporarily more receptive during recovery.
Which skin types and concerns benefit from PDRN-serums?
PDRN skincare is generally well tolerated, though it’s worth noting that many formulas are derived from salmon DNA, so those who are vegan or avoid fish-derived ingredients may prefer plant-based alternatives. Otherwise, it suits most skin types and is particularly useful when the skin is compromised – whether that’s due to dryness, irritation from overusing actives, inflammatory conditions such as rosacea or eczema, or post-treatment recovery. In these situations, PDRN works best as a reinforcing step, helping to restore comfort and support overall skin resilience.
