What is PDRN or salmon DNA in skincare?
PDRN (polydeoxyribonucleotide), sometimes called salmon DNA, is an ingredient trending in Korean skincare and aesthetic treatments, marketed for a smoother, more revitalized look. In cosmetics its effects are described in appearance terms; stronger claims belong to clinical procedures, not over-the-counter products.
What is hyaluronic acid and how do you use it?
Hyaluronic acid is a humectant that draws water into the skin for a plumper, hydrated look. In Korean routines it's best applied to damp skin and sealed with a moisturizer on top, so the moisture it attracts stays locked in rather than evaporating.
What order do you apply Korean skincare?
A general Korean order goes thinnest to thickest: cleanse, then toner, essence, serum or ampoule, eye cream, moisturizer, and sunscreen last in the morning. Lighter, watery layers go on first so they absorb, with richer creams and sun protection sealing everything in.
