5 PDRN Collagen Intense Vitalizing SerumCOSRX 5 PDRN Collagen Intense Vitalizing Serum 50 ml (1.7 fl oz)

Aimed at tired, dull-looking skin

This serum is aimed at several visible concerns at once: dullness, rough or uneven texture, fine lines, dryness and skin that looks tired or less firm. The brand reports results from its own testing for radiance and firmness; as with any cosmetic, changes build with regular use and differ between people.

Five sources of PDRN

The formula draws its PDRN from five different origins: salmon DNA, green caviar, rice, lactobacillus and centella asiatica.

Collagen at 200 Da

Low-molecular-weight collagen, given as 200 Da, sits alongside the PDRN complexes. COSRX positions this as more than a basic hydrating or glow serum, with a focus on skin that looks smoother, bouncier and more defined around the forehead, cheeks and jawline.

How to use

After cleansing and toner, apply a few drops of the serum to clean skin and press it in until absorbed. Follow with your moisturiser. For external use only.

Before you choose

This is a cosmetic serum, not a medical or in-clinic treatment. For external use only. One of its PDRN sources is salmon DNA, so it is not suitable if you avoid fish-derived ingredients. No directions or full ingredient list are given in the listing, so check the pack before use. Korean-market product: packaging may show Korean text.
