Cosrx - The 6 Peptide Skin Booster 150ml

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.
