COSRX The Blue Peptide Bakuchiol Plump Glow Serum 50ml, Pack of 2

Features

The Blue Peptide Bakuchiol Plump Glow Serum 50ml, 2 Pack by COSRX features a naturally blue-toned formula designed to deliver pore, texture, and blemish care. Formulated with non-flowing viscosity, this dual-functional serum provides brightening and wrinkle care benefits, leaving the skin glowing and healthy-looking without heavy residue. When pairing this serum with vitamin C products, such as vitamin C 13 or 23 serums, it is recommended to apply them at different times of the day (morning/evening) to optimize skin absorption and efficacy.

Benefits

This serum provides deep hydration and plumping benefits, enhancing firmness, smoothness, and radiance. It targets total pore concerns—including pore density, surface area, depth, horizontal pores, vertical pores, and sagging aging pores—while addressing dark spot marks and rough texture. By coating the skin with moisture and density, it prepares the complexion for seamless makeup application, improving makeup adherence, coverage uniformity, and longevity.
