Quick answer
What Is a Salmon DNA Skin Booster?
A salmon DNA skin booster is an injectable containing purified DNA fragments – PDRN (polydeoxyribonucleotide) or the longer-chain PN – extracted from salmon. Placed in the dermis, these fragments are thought to support the skin's natural repair, helping it look calmer, firmer and more even.
Salmon DNA boosters have been used in Korean clinics for many years, and several brands exist. RE20 is the salmon DNA booster offered on this page; your doctor will explain its formulation and how it compares with other PDRN and PN products. The best-known PN booster, Rejuran,,000 and may be suggested as an alternative.
Salmon DNA boosters do not add volume or change face shape. They suit people whose skin looks tired, stressed or slow to recover – for example after travel, sun exposure or laser treatments.
