PDRN and salmon DNA serums have been the most-talked-about category in K-beauty for about two years now, but until recently the credible options came from clinics, not Amazon. The SKSOYT Salmon DNA Serum is one of the rare at-home formulations that uses the same polynucleotide actives clinics charge $300 a session for, packaged in a 1 oz ampoule built to pair with a derma roller or pen. We ran it through six weeks on three testers — one in their 30s with early fine lines, one with hyperpigmentation from old acne scars, and one with a dull-skin complaint they couldn’t shake.
About the SKSOYT Salmon DNA Serum
The active is salmon-derived polynucleotides — short DNA fragments that, at the cellular level, signal fibroblasts to produce more collagen and elastin. It’s the same molecule behind Rejuran injectables in Korean dermatology clinics; the at-home version uses topical application paired with a microneedling tool to drive the serum into the upper dermis. SKSOYT’s formula adds hyaluronic acid for immediate plumping and skips fragrance, alcohol, and synthetic dyes. Each 1 oz bottle covers roughly 8–12 microneedling sessions when used twice weekly.
What we like about it
The first thing you notice is the texture: it’s a thin, watery ampoule that absorbs almost immediately rather than sitting on the surface the way thicker serums do. Microneedled in, it goes to work fast. By the end of week two, our hyperpigmentation tester had visibly less redness across the cheeks where old acne scars had been; by week four, our fine-lines tester reported smoother under-eye and forehead texture in the morning. Brightness was the universal finding — all three testers noted a more even, lit-from-within skin tone within a week of use.
By week three my skin looked like I’d had a facial — texture is smoother and my acne scars are visibly lighter.Verified buyer
It plays well with the rest of your routine
We tested SKSOYT layered under both retinol routines and acid-heavy routines, and the formula held up. No pilling, no stinging on freshly-microneedled skin (which is a real risk with fragranced serums), and no interaction with the retinoid that one tester continued using on alternate nights. The hyaluronic acid buffer is part of why; it gives the salmon DNA a clean carrier instead of fighting for space with five other actives.

What could be better
The 1 oz size disappears faster than the price suggests it will, especially if you’re using it with a microneedling pen twice a week — plan on a fresh bottle every six to eight weeks for sustained use. And while you can apply it without a microneedling tool, you’ll wait twice as long for results. If you don’t already own a derma roller or pen, factor that into the cost of trying it.
Should you buy the SKSOYT Salmon DNA Serum?
If you’ve been priced out of clinical PDRN treatments but want the same active class on your skin at home, this is the cleanest at-home formula we’ve tested in the category. Pair it with a derma pen and you’re getting close to clinic-grade results on a drugstore budget.
