Latest Trend: Salmon Sperm In Your Skincare? Here’s The Explanation According To Professionals


(USA Today) Once, there was snail mucin, the viral Korean skincare ingredient. The latest “it” product? Salmon testicle DNA.

More professionally known as “salmon pdrn,” salmon testicle DNA has been found in many luxury K-beauty products, including the KAHI Wrinkle Free Multi Balm, which has been popularized in TV shows like Netflix’s “Extraordinary Attorney Woo” and in Doja Cat’s “Vegas” music video. As the name implies, you glide the balm across your face for a dewy, luminous look.


Coating yourself with fish genital DNA may sound questionable, but beauty experts, along with an abundance of research, support its regenerative, anti-inflammatory effects; One study found that salmon sperm was associated with increased skin elasticity and stronger collagen levels – both of which are crucial for anti-aging skin.

“Having an open mind to these different types of ingredients can be really great. There are a lot of ingredients we’re not used to in North America that are very popular in Korea, and there’s a reason why they do: There’s a lot of evidence behind its benefits,” says Kenna Whitnell, a biochemist and research scientist.

What is salmon pdrn, and how does it work?

Salmon pdrn, which stands for “polydeoxyribonucleotides,” is sperm DNA most commonly derived from salmon trout or chum salmon. Whitnell, who specializes in skincare consulting, says it works by targeting a specific protein that, when stimulated, promotes wound healing.

Some may wonder: Why the testicles? Whitnell says the genital area contains a high amount of DNA, making its extraction easier and more cost-efficient.

As for why salmons specifically, “the DNA of salmon is very close to that of humans, so it has a high compatibility with our own cellular functioning,” Whitnell explains. “The extraction and purification process removes active proteins and peptides that could potentially cause immune reactions. So it is just very purely DNA and that doesn’t contain (anything) that could interact with our skin in a bad way.”

Salmon pdrn is an ingredient in many K-beauty products that helps promote skin elasticity and anti-aging.

What are the skincare benefits of salmon testicle DNA?

Research has lauded salmon testicle DNA for its ability to restore skin elasticity, repair moisture barriers and reduce inflammation, making it a viable option for those with damaged or dry skin.

“This ingredient is great because if you have a cut, wound or acne blemish that is healing, salmon pdrn could help with that,” medical esthetician Cassandra Bankson explains about the process called “cell migration.” “White blood cells will attempt to fix this wound … and (salmon pdrn) has been shown in research to help with that cell migration, or bringing the healing cells to that affected area.”
