COSRX The 6 Peptide Skin Booster is a lightweight, water-like serum designed to be the very first step of your routine. This booster helps prep the skin, allowing all following serums and moisturizers to absorb more effectively.
Formulated with a blend of six targeted peptides, niacinamide, and hydrating amino acids, it works to refine pores, balance oil, smooth skin texture, and support an overall brighter, healthier complexion.
It’s suitable for all skin types—especially those dealing with multiple concerns such as excess sebum, enlarged pores, dullness, fine lines, sensitivity, and uneven tone.
