Salmon Sperm, For Skincare? Dr. Green Featured in Provoked Magazine

The article looks at PDRN (polydeoxyribonucleotide), the salmon-sperm-derived skincare ingredient popularized by Korean skincare brands such as Rejuran. Now everywhere from K-beauty to Lancôme, PDRN promises firmer, smoother, more hydrated skin. Dermatologists interviewed acknowledge it has real potential — supporting collagen production, wound healing, reduced inflammation, and skin barrier repair — but the catch is that most supporting research involves injectable versions (used in South Korea but not FDA-approved in the US) or lab and animal studies, not the topical creams and serums most consumers would actually buy.

The core problem with topical products is molecular size: PDRN molecules are generally far too large to penetrate intact skin, meaning serums likely sit on the surface rather than working “at the cellular level” as marketed. Facials that pair PDRN with microneedling or lasers may improve absorption, but evidence there is still limited.  The advice: stick with proven staples like vitamin C, retinoids, and sunscreen, and for those wanting a more intensive treatment, microneedling with platelet-rich plasma (PRP) has stronger data behind it than the salmon sperm facial.

“By supporting the skin’s natural repair processes, salmon PDRN may help improve skin texture and tone, enhance hydration, reduce the appearance of acne scars, soothe sensitive skin, and promote firmer, more resilient-looking skin,” noted Dr. Green in the article available at https://provokedmagazine.com/should-you-slather-your-face-with-salmon-sperm/
