Why TikTokers Are Injecting Salmon Sperm Into Their Faces

Scroll through TikTok or Instagram, and you'll find influencers swearing by unconventional treatments, posting dramatic before-and-after photos and glowing testimonials about their rejuvenated skin. And the skincare "It Girl" of the moment? It's salmon sperm. Yeah.

As we kick off the new year—prime time for beauty resolutions!—a growing number of people are seeking out "salmon sperm facials." Before your imagination paints an extra fishy picture (pun intended), understand that people aren't really smearing straight-up salmon sperm on their face. The secret ingredient is something called PDRN, or polydeoxyribonucleotide, a compound extracted from salmon DNA. So, what exactly is this secret ingredient, and is it truly the next frontier in anti-aging skincare?

The science behind the hype

PDRN isn't totally snake oil; the compound has legitimate clinical backing for its regenerative properties. Research suggests that PDRN can stimulate tissue repair, promote collagen production, and improve skin elasticity by activating adenosine receptors in cells. Several sources claim it's been used in medical applications since the 1980s in Italy and South Korea. Whatever the actual origins, PDRN has gradually made its way into mainstream skincare.

The treatment typically involves a series of micro-injections delivered directly into the skin, similar to mesotherapy or microneedling procedures. In the U.S., however, PDRN is only legal to use topically, since the FDA qualifies it as a beauty product and not a drug. Proponents claim it can reduce fine lines, improve skin texture, minimize scarring, and create an overall more youthful appearance. Unlike other cosmetic procedures that simply fill or temporarily plump the skin, PDRN is said to actually stimulate the skin's natural healing processes. But as always, there's a significant gap between reality and what you see online.

The reality check

Social media thrives on transformation narratives, and skincare content is no exception. The algorithms favor dramatic reveals, leading creators to emphasize stunning results while downplaying less glamorous details—like the fact that these injections can be quite painful according to some. "While PDRN has legitimate clinical data supporting skin repair and regeneration," says Dr. Claudia Kim, "viral content often exaggerates results and glosses over who is—and isn't—an appropriate candidate. Context and medical supervision matter." When it comes to the injections specifically, these treatments can cause temporary swelling and bruising. At the very least, they could require multiple sessions to see results.

Again: If you're in the U.S., and there's a syringe full of salmon sperm headed straight for you, it might not be FDA-approved. That means its purity, safety, and effectiveness are not regulated. As with any medical aesthetic procedure, you shouldn't sign up for PDRN treatments without careful consideration—considerations that extend beyond the promise of better skin. Do you know which salmon DNA procedure you're signing up for? Is it an injection, or is it technically microneedling? Did you opt for PDRN or PN (polynucleotides), a purer and more concentrated form of PDRN? To make things even more confusing, these treatments can go by different names, from “salmon skin facials,” to “salmon sperm injections,” or “PDRN facials” to the brand name Rejuran. One thing is sure: As demand grows, so does the risk of unqualified practitioners offering the treatment, potentially leading to complications or disappointing results.

The bottom line

The salmon sperm trend may sound bizarre, but there is science backing it up. And when your favorite beauty influencer credits their glowing skin to a specific treatment, it's tempting to believe you can achieve the same results. Social media will always continue to drive beauty trends, and there's nothing inherently wrong with being inspired by what you see online. But for your looks and your safety, you need to understand the difference between a carefully curated social media moment and the full reality of medical aesthetic procedures.

If you're intrigued by PDRN treatments after seeing them online, consult with a qualified dermatologist or licensed aesthetic practitioner. They can assess whether you're an appropriate candidate, explain realistic expectations, discuss potential side effects, and ensure the treatment is administered safely. As more advanced treatments become increasingly accessible and visible online, don't let TikTok influencers replace professional medical consultation.
