Description
COSRX The 6 Peptide Skin Booster Serum is a lightweight, water-based serum used right after cleansing, in the toner step, to boost the serums and ampoules that follow. Six peptides - Acetyl Hexapeptide-8, Copper Tripeptide-1, sh-Polypeptide-121, Dipeptide Diaminobutyroyl Benzylamide Diacetate, Oligopeptide-68 and Palmitoyl Tripeptide-8 - work with hyaluronic acid, N-acetylglucosamine and allantoin to support the look of elasticity, texture and radiance.
Niacinamide and adenosine join a blend of amino acids for hydration and a smoother-looking surface. The texture is a toner-type feel that absorbs instantly without stickiness, and the brand describes it as suitable for all skin types, with sensitive skin irritation and non-comedogenic testing completed. Pat it on morning and night before your ampoule, serum or moisturizer.
