COSRX The 6 Peptide Skin Booster Serum (150 ml) is a lightweight, watery booster serum with six powerful peptides, niacinamide, and hyaluronic acid—ideal as a first step after cleansing. It provides lasting hydration, visibly firms, reduces the appearance of wrinkles, and improves skin texture and tone. Its velvety texture absorbs quickly, is non-sticky, and forms the perfect base for subsequent skincare.

Application: Apply to face and neck as the first step in the morning and evening after cleansing. Gently massage in, then layer with serum or cream. Use multiple pumps for extra intensity if needed.
