COSRX's The 6 Peptide Skin Booster Serum is a multi-tasking K-Beauty serum powered by 6 Peptides, Hyaluronic Acid, NAG and Amino Acids to even skin tone, deeply hydrate, firm, smooth and refine pores — all in one lightweight daily booster that delivers complete skin transformation from the very first application.

Description

Six peptides. One serum. Total skin transformation.

Introducing COSRX The 6 Peptide Skin Booster Serum — a comprehensive K-Beauty serum that delivers six targeted peptides alongside a powerful supporting cast of Hyaluronic Acid, NAG (N-Acetyl Glucosamine) and Amino Acids to address every major skin concern in one elegant formula. From evening skin tone and boosting hydration to firming, smoothing, controlling sebum and refining pores — this serum does it all.

Peptides are short chains of amino acids that act as messengers in the skin, signalling cells to produce more collagen, elastin and other structural proteins. With six distinct peptides working simultaneously, this serum targets multiple signs of ageing and skin imbalance at once — making it one of the most efficient and cost-effective anti-ageing serums available at any price point.

Hyaluronic Acid delivers intense hydration at multiple skin depths, while NAG (a brightening and barrier-supporting ingredient) helps fade hyperpigmentation and supports skin renewal. Amino Acids nourish and strengthen the skin from within, improving overall resilience and texture. Together, this ingredient complex creates a serum that is genuinely hard to replace — a true all-in-one daily booster for anyone serious about their skin.
