The 6 Peptide Skin Booster Serum

Your first-step serum for firmer, smoother, brighter skin.

The COSRX 6 Peptide Skin Booster Serum is a multi-functional, lightweight serum formulated to prep, protect, and transform your skin. Powered by a 6 Peptide Complex, this innovative booster improves skin elasticity, tightens the appearance of pores, and smooths fine lines and rough texture — all while prepping the skin for deeper absorption of the rest of your routine.
