COSRX The 5 PDRN Collagen Intense Vitalizing Serum
Sodium DNA at 10 of 38 is one of the highest placements we found in a serum. COSRX's 'five PDRNs' appear as just two DNA lines on the label.

Where the PDRN sits on the label
- The DNA ingredients on the label: Sodium DNA (ingredient 10 of 38) and Hydrolyzed DNA (ingredient 29 of 38).
- There is no preservative with a legal 1% cap on this list to measure against, so the label alone can't place the DNA above or below 1%.
- No fragrance or parfum is listed.
How we read ingredient lists →
Our read
Sodium DNA is tenth, right after niacinamide, 1,2-hexanediol, betaine and panthenol, a genuinely prominent position. A second line, Hydrolyzed DNA, appears at 29.
COSRX markets five PDRN sources: salmon, centella, rice, lactobacillus and sea grape. There's no rice or sea-grape ingredient on the list, so those sources can only be counted inside the two DNA lines, and COSRX doesn't say which is which. It's fragrance-free.
Good fit if
Anyone who wants a fragrance-free serum where DNA ranks in the top ten.
Skip it if
You specifically want salmon-only PDRN. The sources here are blended and undisclosed per line.
