Elevate your entire skincare routine with the multi-action COSRX The 6 Peptide Skin Booster Serum Duo Set. Featuring two full-sized bottles for a total of 300mL, this high-performance first-step serum functions as a powerful skin booster to amplify the results of any skincare steps that follow. Formulated with a proprietary blend of 6 potent Peptides, Hyaluronic Acid, NAG, and Amino Acids, it targets multiple skin concerns simultaneously. It absorbs instantly like a refreshing toner but works deeply like an intensive serum to smooth out rough texture, control sebum, minimize pores, and restore a firm, radiant bounce to tired skin.
