Product details

Peptides and bakuchiol in one daily step

COSRX pairs GHK-Cu copper peptides with bakuchiol in this serum, a combination aimed at skin that is starting to show early changes such as reduced bounce, enlarged-looking pores and uneven texture. The brand describes the bakuchiol as low-irritation, so the formula is intended for everyday use rather than occasional treatment nights.

Moisture with a plumper, glowing finish

The serum is designed to replenish hydration so the complexion looks plumper, smoother and more radiant. It can also help refine the look of dullness and lingering post-blemish marks as part of a regular routine.

Planning it around other actives

Because the formula carries a high concentration of peptide-based actives, COSRX recommends keeping it apart from strong vitamin C products. A simple approach is to use this serum in the morning and save vitamin C for the evening. The bottle holds 50 ml (1.69 fl oz).

How to use

Apply a few drops to clean skin in the morning or evening. Do not use it in the same routine as vitamin C, direct acids or retinoids.

Before you choose

This is a leave-on serum that needs a separate slot in your routine from vitamin C and acids. For external use only. Patch test on the body before applying to the face. Korean-market product: packaging may show Korean text.
