Peptide booster serum for firmness and enhanced skincare absorption

COSRX The 6 Peptide Skin Booster Serum is a lightweight toner-serum hybrid that smooths, hydrates, and improves skin elasticity while enhancing the performance of the following skincare steps. The watery texture absorbs quickly without stickiness, helping to refine pores, even out tone, and restore the skin’s moisture barrier. Pairs perfectly with active products containing vitamin C, retinoids, or niacinamide.
