Whereas salmon sperm, aka PDRN, seems like pure clickbait, it’s the ingredient dominating skin-care conversations proper now, and the science behind it spans many years.

Whereas PDRN (polydeoxyribonucleotide) looks as if a contemporary Ok-beauty innovation, New York dermatologist Elaine Kung, MD says its therapeutic roots date again to the Nineteen Eighties in Italy. “Researchers originally explored PDRN for its profound regenerative capabilities in wound healing,” she explains. Within the Nineteen Nineties, a Korean firm referred to as PharmaResearch started utilizing PDRN as a pharma ingredient, specializing in wild salmon in a selected province of Korea.
“PharmaResearch pursued the localization of PDRN production technology using this source,” says Seul-ong Ohk from the Strategic Analysis Planning Crew on the PharmaResearch R&D Heart. “The structure of salmon DNA is highly similar to that of human DNA, allowing it to function effectively in the body with a low risk of side effects. In particular, the salmon’s reproductive cells are rich in nucleic acids that play an important role in supporting skin health.”
2009: High quality Management
After years of analysis, PharmaResearch developed its patented DOT—DNA Optimizing Expertise—which Ohk says can course of extremely purified salmon-derived DNA into numerous types (skin-care merchandise, injectables and extra) below strict high quality management. “What makes PDRN interesting is how it works on a cellular level,” says Minneapolis dermatologist Jenny Liu, MD. “It helps activate specific receptors in the skin that reduce inflammation and promote healing, and it also provides building blocks that skin cells can use to repair themselves and regenerate.”
2014: Injectable Breakthrough
The leap from medical wound care to aesthetic medication occurred in South Korea. “Cosmetic researchers realized that the exact mechanisms healing severe wounds could be harnessed to reverse signs of aging,” says Dr. Kung. “This culminated in 2014 when PharmaResearch launched an injectable called Rejuran. By utilizing polynucleotides (PN), it revolutionized the ‘skin booster’ category and became a global phenomenon.”
Ohk explains that what’s also known as “injectable PDRN” is, the truth is, a PN-based medical system, reminiscent of Rejuran and Rejuran HB Plus. “PN is a high–molecular weight material, and when injected into the skin, it can help improve skin texture by supporting hydration and providing physical support within the dermal layer,” he says.
Although these injectables are broadly utilized in many components of the world (Asia is the most important market by far), they’re at present not but FDA-approved in the US. “The strongest data we have on salmon DNA is for its injectable forms,” Dr. Liu says. “We’re seeing meaningful results in terms of collagen production, healing, and even improvements in fine lines or pigmentation over time, which is why it’s become popular in regenerative aesthetics.”
2017: Topical Takeover
PharmaResearch made its foray into topical merchandise in 2017, launching its signature Rejuran Turnover Ampoule ($52) in Korea (it launched within the U.S. this previous March). Ohk says Rejuran’s topical merchandise include c-PDRN, which is manufactured in a decrease molecular weight in comparison with PN. “This allows for relatively better skin absorption when applied topically,” he explains.
Rejuran sparked a worldwide development, inspiring different manufacturers to launch topical PDRN serums, lotions, masks and extra. “These products are much more limited because these DNA fragments are relatively large and don’t penetrate skin as deeply,” Dr. Liu says. “They can still help with hydration and barrier support, but they’re not going to replicate the effects of in-office treatments. PDRN skin care is a promising category, but we need more standardized data, especially when it comes to long-term outcomes and optimal use.”
2024: Vegan PDRN
Because the demand for sustainable, ethically sourced and vegan merchandise surges, the skin-care house is innovating quickly. “Because traditional PDRN is animal-derived, vegan brands are creating brilliant alternatives designed to bio-mimic the effects of salmon DNA,” says Dr. Kung. “There’s phyto PDRN—DNA fragments from resilient plants, like Korean ginseng—and also bio-fermented PDRN, or biotech PDRN. This is the bleeding edge of cosmetic chemistry. Using microbial fermentation—often utilizing specific bacteria or microalgae—labs are cultivating highly purified polynucleotides.” Nonetheless, whereas the medical literature supporting salmon-derived PDRN is many years deep, Dr. Kung factors out that knowledge on these vegan options continues to be rising.
2025 – 2026: Enhanced Outcomes
Equally to how PRP (platelet-rich plasma) or exosomes might be utilized after in-office remedies like microneedling and lasers, PDRN will also be used. In early 2025, an organization referred to as Prollenium launched VAMP, a patent-pending, topical PDRN resolution that’s meant to be paired with microneedling to enhance pores and skin elasticity, hydration and radiance.
This March, it launched VAMP Superior, a next-gen model that includes 5 occasions extra medical-grade, high-purity, 0.5-percent PDRN, together with amino acids, nutritional vitamins, minerals and hyaluronic acid. Dr. Tim Lee, chief scientific officer at Prollenium, says it may be used to enrich and improve the outcomes of in-office facial remedies. “This approach isn’t about immediate transformation, but rather gradual, progressive improvement,” he explains. “Optimal results are typically seen after at least three treatments administered monthly. Over time, patients notice better hydration, smoother texture, improved elasticity and an overall healthier skin appearance.”
The Future: What’s Subsequent
Although getting FDA approval for PN injections within the U.S. could also be a pipe dream, PDRN skin-care merchandise are shifting full steam forward, and we’ll be seeing a bunch of latest codecs, primarily stemming from Ok-beauty. “PDRN is at the forefront of the future of regenerative aesthetics, which is moving beyond simply ‘filling’ wrinkles and toward skin repair that actually turns back the clock on its biological age,” says Dr. Kung. From topicals to injectables and past, we’re simply scratching the floor of this trending ingredient and are excited to see what comes subsequent.
