Is Salmon DNA A Skincare Fad Or The Secret To Healthy Skin For Older Women? We Asked A Dermatologist

As with every seasonal change, the skincare side of TikTok has latched onto a buzzworthy new ingredient: PDRN. More commonly known as "salmon DNA" or "salmon sperm," the ingredient has been popping up in face masks, serums, and med-spa service menus. Skincare brands are marketing PDRN-based products as having a wide array of benefits, including skin smoothing and radiance-boosting properties. But like many skincare fads that eventually end up doing more harm than good, consumers are wondering whether this is actually a game-changer or just another viral beauty moment.

We spoke with Stamford, Connecticut board-certified dermatologist Dr. Annette Czernik, who tells us PDRN is valued for its potential restorative abilities. "It's being marketed as a regenerative ingredient that may help reduce inflammation while improving hydration, supporting collagen stimulation, and reducing redness and pigmentation," she says. 

After age 40, skin tends to heal more slowly and thins after procedures like lasers or microneedling — even if they're skincare treatments with minimal recovery time. While salmon DNA has been used quite extensively in South Korea, often as an injectable combined with hyaluronic acid, it is not FDA-approved for intradermal use in the United States, so the ingredient is limited to topical or post-procedure applications.

Understandably, there's a lot of interest in PDRN, as skincare routines for those over age 40 often aim to increase cellular turnover. But the popular salmon-based ingredient isn't well tested. While the use of PDRN may help to improve hydration and texture while reducing post-procedure recovery, Dr. Czernik says the science is still limited. "There are no randomized controlled studies showing significant long-term anti-aging benefits from topical PDRN... [It's] certainly not a replacement for proven ingredients like retinoids, sunscreen, or collagen-stimulating procedures," she says. So, while it may offer short-term soothing, its promised long-term anti-aging impact has yet to be proven. 

Although marketed as a holy-grail ingredient, Dr. Czernik notes that it could be most impactful when paired with in-office microneedling. However, PDRN is not without its downsides. Some patients face the risk of allergic contact dermatitis, so Dr. Czernik suggests using platelet-rich plasma (PRP), which does not pose the same risk.

For consumers dying to try it, you might not want to fill up your cart with masks, toners, and creams just yet. "Don't buy into the hype," Dr. Czernik concludes. Instead of chasing a trending ingredient, she emphasizes building a consistent skincare routine with tried-and-true products: Sunscreen, antioxidants, retinoids, and proper hydration — the most reliable path to long-term skin health.
