Is it worth including the "salmon sperm" that Kim Kardashian raves about in your skincare routine?

Kim Kardashian's admission that she uses salmon sperm for her facial has sparked mixed reactions online, from shock to intrigue. But as unusual and bizarre as it may sound, Kim may be on the right track. PDRN, short for polydeoxyribonucleotide, is finding its way into skincare formulas and is being talked about everywhere. Salmon DNA (yes, usually from salmon sperm) is known for its powerful regenerative properties, Vogue reports.

The science behind PDRN

The compound derived from salmon is very similar to human DNA, which makes it so compatible with our cellular functions. Originally used in medical settings to treat chronic conditions such as burn wounds, diabetic ulcers, and post-surgery recovery, it has 20 years of experience in regenerative medicine. “PDRN has a strong scientific application,” says Dr. Shehzadi Kohli, a plastic and aesthetic surgeon.

Studies have shown that when injected, the active ingredient can significantly speed up healing. “It’s a skin-healing agent after procedures like lasers or peels,” he adds. And that’s not all, the active ingredient also reduces inflammation, increases blood circulation by stimulating the formation of new blood vessels, and keeps the skin clear by accelerating the natural turnover of skin cells.

This is especially helpful if your skin is tired, damaged, or just starting to show signs of aging, such as fine lines and sagging. Dr. Kohli explains that at a cellular level, PDRN stimulates fibroblasts, the cells responsible for collagen production, which helps repair damage, improve elasticity, and restore the skin’s natural firmness.

Injections or serums

While PDRN’s ability to boost collagen levels is well-documented in injections, the reality is a little different when it comes to creams and serums. A formula’s effectiveness depends on its molecular delivery system—in short, how well it absorbs into the deeper layers of the skin.

Is PDRN right for you?

While PDRN is generally well-tolerated, people with sensitive skin should approach the active ingredient with some caution. For example, given its origin, those with severe fish allergies may want to steer clear of it. And while PDRN may help fade acne scars over time, if you're dealing with an active breakout or skin infection, you should consult a dermatologist before adding it to your regimen.
