What Does PN Mean in Skincare? Polynucleotides Explained
Polynucleotides: longer chains from the same DNA fragment family as PDRN. In clinics the word usually means an injectable; on a serum it means a topical cousin of PDRN.
On the label
PN, polynucleotide or sodium DNA. On a serum, treat it as PDRN under another name and judge the rest of the formula.
What it does not mean
It does not mean the serum is a clinic treatment in a bottle. Injected and applied are different things, and the label borrows the glow of the first.
