What Is PDRN in Skincare? Why Is Everyone Obsessed with Salmon DNA?

There’s a new skincare ingredient swimming its way into everyone’s top shelf, and no, you’re not dreaming when you hear the words “salmon DNA”. It’s real. It’s powerful. And it’s called PDRN. So what is it, why is it trending, and should it be in your routine? Let’s dive into the glow science

What Is PDRN?

PDRN stands for Polydeoxyribonucleotide, and it is a naturally derived molecule extracted from salmon DNA. It may sound like a biotech buzzword, but it’s been used in Korean dermatology clinics for years to speed up wound healing and skin regeneration.
Think of it as your skin’s best friend when it comes to repairing, firming, and renewing from within.

What Does PDRN Do for Your Skin?

PDRN is a multitasking powerhouse. Here’s what it does:

Speeds up skin cell regeneration (perfect for dull or tired skin)
Reduces fine lines and wrinkles
Boosts elasticity and firmness
Improves skin texture and hydration
Soothes inflammation, which is great for post-acne marks or redness

In short: PDRN gives your skin that “reborn” glow.

Why Is Everyone Talking About Salmon DNA Now?

It’s all over TikTok. It's raved about by Korean dermatologists. Salmon DNA is rich in nucleotides—the literal building blocks of skin regeneration. As skincare becomes more about repairing your barrier (and not just stripping it), PDRN is stepping into the spotlight.
Pair that with a few standout K-beauty formulas, and it’s no wonder it’s trending.
