About the product

This multifunctional serum from the Korean brand Cosrx contains 6 peptides to address various skin needs, such as improving texture, regulating sebum production, and caring for pores, among others.

Thanks to the properties of its ingredients, this serum has brightening, calming, and firming properties. It contains niacinamide, known to help improve pigmentation and regulate sebum production. It also contains N-acetylglucosamine, an ingredient that helps exfoliate the skin, and adenosine to improve elasticity, treating small wrinkles and fine lines. In addition, it contains hyaluronic acid for hydration, NMF to improve the skin barrier, and allantoin to soothe the skin.

The 6 Peptide Skin Booster Serum is an ideal product for evening out skin tone, restoring smoothness, and providing a natural appearance.

It's a very light, non-comedogenic serum that leaves a refreshing feeling on the skin after application. It glides easily over the skin and its scent is almost imperceptible.

How to use

Apply 2 to 3 drops of the serum to clean skin and, using your fingertips, distribute the product all over your face, gently massaging until completely absorbed.
