Cosrx 6 peptide skin booster serum is a lightweight, toner-like facial serum that helps improve skin firmness, texture, and overall radiance.

Formulated with six powerful peptides, it hydrates the skin while helping to reduce the appearance of fine lines, enlarged pores, and uneven skin texture. Suitable for all skin types, this serum absorbs quickly and layers easily with the rest of your skincare routine.
