Salmon DNA Takes Over Skincare
By Kelli Luu | 15 Apr, 2026

PDRN was once used to heal burns, but now it has become a skincare favorite in the K-beauty world as it takes anti-aging and skin repair to another level.

There’s a new skincare ingredient that has blown up in Korea and is making its way to skincare shelves in America and it’s something you may not expect. It’s salmon DNA or PDRN. 

PDRN is short for polydeoxyribonucleotide, salmon DNA that’s most commonly extracted and purified from salmon sperm. But this is not just another skincare trend, its science backed. PDRN was first discovered in the early 1980s in Italy and was used to treat burns and other stubborn wounds. 

Enter Koreans in the mid-2000s. Korean dermatologists and doctors began to experiment with PDRN in skincare. They were able to recognize that PDRN has regenerative properties that can be applied to the skin to help with procedure recoveries, repairing acne scars, and boosting collagen production. 

The way PDRN works is by activating what’s called the adenosine A2A receptor, which is basically a pathway in our bodies that tells the skin to repair and regenerate itself. Once that signal is triggered, it stimulates fibroblasts which are the cells responsible for producing collagen. PDRN also promotes angiogenesis, the formation of new blood vessels that helps with circulation in the skin. Lastly, PDRN reduces inflammation, making it a popular choice for calming acne-prone skin. 

Using PDRN in your skincare routine can overall result in better texture and improved elasticity and that is exactly why it became such a hit in South Korea. PDRN fits right into the K-beauty philosophy that focuses on repairing the skin at a deeper level. 

While the most dramatic results come from injectable PDRN treatments done in clinics, many brands incorporate it in topical skincare and now, it’s making its way to global shelves. So if you see PDRN listed in your skincare, just know it’s not another viral trend, but a bigger step toward regenerative skincare.
