cosrx The 6 Peptide Skin Booster Serum 150ml

Six peptides, one bottle. The COSRX The 6 Peptide Skin Booster Serum is built around a straightforward idea: tackle several skin concerns at once — texture, radiance, firmness, comfort — without making your routine any heavier. 150 ml so you never have to hold back.

Texture and ingredients — The formula combines six peptides, each with a distinct and verifiable role. SH-Polypeptide-121 supports collagen production for a plumping effect; Copper Tripeptide-1 refines skin texture. Dipeptide Diaminobutyroyl Benzylamide Diacetate targets excess sebum and the appearance of pores, while Oligopeptide-68 works on evening out skin tone. Palmitoyl Tripeptide-8 soothes and reduces skin sensitivity; Acetyl Hexapeptide-8 smooths fine lines and supports firmness. The texture is lightweight and non-sticky, absorbing quickly — designed to sit seamlessly under everything that follows.

How to use it — It goes as the very first step, right after cleansing, on clean skin that's still slightly damp. Apply it all over the face and let it absorb. The 150 ml bottle means you can be generous: the brand recommends layering multiple applications to help the skincare products that follow — serums, ampoules — absorb more effectively. Think of it as getting your skin ready rather than finishing your routine.

• Six peptide actives with distinct functions: plumping (SH-Polypeptide-121), retexturising (Copper Tripeptide-1), pore and sebum control (Dipeptide Diaminobutyroyl Benzylamide Diacetate), brightening (Oligopeptide-68), soothing (Palmitoyl Tripeptide-8), smoothing and firming (Acetyl Hexapeptide-8).
• Lightweight, non-sticky texture that absorbs fast — suitable for all skin types and all routines.
• 150 ml size: designed for daily use with no need to ration, including when layering multiple applications.
• Use before any other treatment — active serum, ampoule — to help boost their effectiveness, as recommended by the brand.
• A good fit for anyone looking to address multiple skin concerns without adding extra steps.
