Copper peptide meets bakuchiol in a lightweight glow serum that helps skin look plumper and firmer and pores look smoother, for a glass-skin finish
COSRX's Blue Peptide Bakuchiol Plump Glow Serum pairs 0.5% copper tripeptide-1 (GHK-Cu), the naturally blue peptide behind its colour, with 0.25% bakuchiol, a plant-based alternative to retinol. A five-peptide complex, collagen and five types of hyaluronic acid round out the formula. The fluid texture glides on and leaves skin looking plumper, smoother and more even, with a luminous, glass-like glow that is gentle enough for sensitive skin.
