Medicube PDRN Pink Collagen Bubble Serum 95 ml – Foaming serum with PDRN & Triple Collagen The Medicube PDRN Pink Collagen Bubble Serum is an innovative K-beauty serum in a generous 95ml format. The two-phase formula is shaken before use and transforms into a milky-pink, lightly foaming texture that spreads pleasantly on the skin. Sodium DNA, also known as PDRN, supports a more vital and regenerated appearance of the skin. The triple collagen complex with collagen, collagen extract, and hydrolyzed collagen contributes to a plumper, more elastic, and more nourished-looking complexion. Niacinamide promotes a more even complexion and helps refine the appearance of pores. A mild dose of retinol complements the formula and contributes to smoother-looking skin, particularly with fine lines. Ceramide NP supports the skins natural barrier and helps reduce moisture loss. The combination of essence and oil phases provides a smooth finish, while cyanocobalamin gives the formula its characteristic pink color.
