Fewer wrinkles, more bounce, a radiant glow—that’s the promise. Two dermatologists on whether the fish-based miracle does anything once it hits your face.
When Kim Kardashian revealed she’d gotten a salmon sperm facial in 2024, the internet reacted exactly as you’d expect. Most people lambasted the absurdity of the star ingredient. Yet some made a beeline to their local medspa, influenced to try the ridiculous-sounding (yet potentially glow-getting) treatment for themselves.
Kris Jenner, 70, recently followed in her daughter’s footsteps by teaming up with Korean brand Rejuran, which manufactures not only salmon sperm essences used for said facials but also a commercial skincare line. As Jenner said in a November 2025 Instagram video, the line “contains an amazing ingredient,” officially known as polydeoxyribonucleotide or PDRN, “that works on my skin at the cellular level, and it helps my skin repair and regenerate.” She opened the sponcon by saying that she refuses to gatekeep the PDRN ampoules giving her skin “a radiant and healthy look” and “amazing elasticity.” (Missing from the sales pitch is the facelift that the world’s most famous momager underwent months earlier for a purported quarter-million dollars, raising the obvious question of whether a serum or a surgery deserves most of the credit. I’ll trust you to do the math.)
With every move that the Kardashian-Jenner clan makes, the implication is that we’re supposed to be Keeping Up. But even if you do your damnedest to avoid the famous family like the plague, chances are you’ve seen PDRN elsewhere. You’ve almost certainly heard about it if you scroll through SkinTok or have a casual interest in K-beauty. Even if you’re more analog and prefer heritage beauty brands, you still might not be able to avoid it. Heck, even Lancôme is riding the PDRN wave, a sign that we’ve moved well beyond millennial-coded territory: The brand packs the ingredient du jour in its Absolue Longevity Soft Cream, formulated to “extend skin’s youthful look” (though opting to source the material from rose, rather than fish).
The pitch is certainly seductive: fewer wrinkles, more bounce, and smoother skin with a surge of hydration. But before you coat your complexion with the infamous ingredient, it’s worth asking an important question: Is PDRN actually that impressive, or is the truth fishier than we’re led to believe?
Claims to Fame (Beyond Virality)
At its best, salmon PDRN can actually do some heavy lifting for mature skin. According to Forum Patel, MD, FAAD, a board-certified dermatologist at Arya Derm in San Francisco, some of its benefits include collagen synthesis and remodeling (for firmer skin with fewer lines), reduced inflammation, support for wound healing, and rebuilding and strengthening the skin barrier.
“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,” added board-certified NYC cosmetic dermatologist Michele Green, MD.
The Fine Print
As impressive as the benefits sound, we need to zoom in a bit closer to see when and where they actually check out.
Most of the research touting the benefits of PDRN are based on injectable versions, which have been used for more than a decade in South Korea and other markets, but have yet to be approved by the U.S. Food and Drug Administration (FDA). “When injected, salmon PDRN is placed directly into the dermis, increasing the concentration in target tissues and stimulating hydration, collagen production, and elasticity,” Dr. Green explained. Other data supporting the ingredient comes from in-vitro studies (i.e., those in a lab setting) or in animal models, said Dr. Patel. By and large, we’re hearing crickets as far as clinically backed results for topical use go.
Then there’s the salmon sperm facial route, which lies in a middle ground of sorts. It involves creating microinjuries—say, via microneedling or lasers—and cracking open a fresh vial so your newly inflamed skin can soak it up. These treatments “may enhance absorption by disrupting the skin barrier,” Dr. Patel continued, “though this research is still limited and its efficacy is still to be determined.”
Naturally, the most accessible (and least invasive) route is to apply essences, serums, moisturizers, or sheet masks enriched with salmon sperm. Again, there’s no shortage of brands—domestic and international, indie and legacy, budget-friendly and luxury—dipping a toe in these waters. But these PDRN products are the least likely to yield the bounty of benefits outlined above.
PDRN weighs anywhere from 50 to 1,500 kilodaltons—yet, per Dr. Patel, molecules must typically be 500 daltons or less to achieve meaningful absorption. “By that standard, the majority of PDRN molecules are too large to penetrate intact skin effectively,” she said. Think of your skin barrier as airport security stopping PDRN for oversized luggage before it ever reaches the gate. Formulas are more likely to sit on your skin instead of instigating the repair and rejuvenation most brands would lead you to believe is actually happening.
Still, Dr. Green mentioned that these products aren’t completely devoid of merit. “Regular use may help improve skin hydration, smoothness, and overall radiance while supporting the skin barrier,” she said. You’re just unlikely to see the ingredient perform the way it does via injectables—or even when applied immediately after procedures that intentionally disrupt the skin barrier to stimulate repair.
Should You Hop Aboard the Salmon Sperm Trend?
It can be tough to resist jumping on beauty trends, especially when they promise to deliver everlasting youth (not to mention they’re championed by women who have the country’s top dermatologists and plastic surgeons on speed dial). Women in midlife are especially vulnerable to these promises, when fine lines have become deeper residents and bounce has made way for deflation. Suddenly, anything with a promising R-word—repair, revive, restore, reverse—sounds awfully tempting, even when your inner critic knows better. Despite everything you’ve learned from decades of beauty marketing, a quiet voice still wonders: What if this one actually works?
In the case of salmon sperm, perhaps surprisingly, neither of the dermatologists we spoke to gave it a hard pass. Instead, they urged managing expectations and leaning on tried-and-true ingredients for the skin wins you’re seeking.
“The potential utility of PDRN for anti-aging is promising, and the underlying biological rationale is scientifically plausible,” said Dr. Patel. “However, the clinical evidence is not yet strong enough to support broad recommendations.” As you build out your skincare arsenal, she suggested leaning on oldies but goodies. “For women in midlife concerned about dryness, fine lines, and sun spots, I still prioritize vitamin C, retinoids, and sunscreen as the pillars of a good anti-aging regimen.” Sure, they’re not as grabby as salmon sperm, but classics are classics for a reason.
Still itching to do something more intensive? Dr. Green suggests skipping a salmon sperm facial and opting instead for microneedling with platelet-rich plasma (PRP), as it has more data behind it. “Microneedling creates micro-injuries that stimulate collagen and elastin production, while PRP (derived from the patient’s own blood) supports healing and enhances skin rejuvenation outcomes—including improvements in skin texture, fine lines, and overall skin quality,” she said. Like it or not, Kim K. also brought this so-called vampire facial to notoriety over a decade ago. Only time will tell if the salmon sperm facial and its at-home offshoots will have the same longevity or results.
