The claim
Regenerates skin, repairs damage, and delivers injectable-level results from a serum.
What the evidence says
Topical studies are small and mostly mechanistic or combined with other actives, with no independent randomized trial showing durable change from PDRN on intact skin; the molecule is large and poorly absorbed. The injectable versions have their own early evidence and are not FDA approved in the U.S.
Who should skip it
Fish allergy warrants a patch test; anyone expecting injectable results from a serum.
What to do instead, or as well
A retinoid and sunscreen for repair; the procedures desk covers what injectable polynucleotides can and cannot claim.
