COSRX The 6 Peptide Skin Booster Serum 150ml - Firming, Hydration & Skin Texture

Looking for a serum that actually does it all? Meet COSRX The 6 Peptide Skin Booster Serum, your new holy grail for glowing, smooth, and youthful-looking skin. Lightweight, fast-absorbing, and non-sticky, this multi-tasking formula is powered by a unique 6 Peptide Complex—each chosen for its specific skin-renewing benefit.

From boosting collagen and smoothing fine lines to brightening dullness and tightening pores, this serum works hard to improve overall skin texture and elasticity. Whether you're dealing with early signs of aging, rough texture, or uneven tone, this powerhouse formula offers a one-step solution.

Key peptides like SH-Polypeptide-121 help plump and firm, Copper Tripeptide-1 supports skin repair, and Dipeptide Diaminobutyroyl Benzylamide Diacetate targets excess sebum and pore size. Plus, Oligopeptide-68 and Niacinamide work together to restore radiance and clarity. With Hyaluronic Acid for deep hydration and Allantoin for soothing relief, it's gentle enough even for sensitive skin.

Use this dermatologist-tested serum as the first step after cleansing to prep your skin for better absorption of the rest of your routine. Expect smoother, firmer, more radiant skin in just a few drops—morning or night.
