Overview
COSRX The 6 Peptide Skin Booster Serum 150ml is a lightweight first-step serum formulated with six peptides to help improve skin elasticity, smooth the appearance of fine lines, and enhance overall skin condition. Its fast-absorbing texture prepares the skin for the rest of your skincare routine while providing lasting hydration.
Enriched with Niacinamide, Sodium Hyaluronate, Acetyl Glucosamine, Amino Acids, Betaine, Adenosine, and Vitamin E, it helps strengthen the skin barrier, refine skin texture, and promote a healthy, radiant complexion.
Suitable for all skin types. Apply after cleansing as the first step of your skincare routine, gently pat into the skin until fully absorbed, then continue with your toner, serum, or moisturizer.
