The Cosrx The 6 Peptide Skin Booster Serum offers a versatile formulation combining six distinct peptides to target multiple common skin concerns simultaneously. The transparent serum texture absorbs comfortably without feeling heavy, making it well-suited for all skin types and warm South African weather. Key active components include SH-Polypeptide-121 for collagen boosting and plumping, alongside Acetyl Hexapeptide-8 to help smooth fine lines and improve skin firmness. To address texture and dullness, Copper Tripeptide-1 retexturizes the skin while Oligopeptide-68 aids in brightening. For oily or sensitive skin, Dipeptide Diaminobutyroyl Benzylamide Diacetate targets excess sebum and pore care, while Palmitoyl Tripeptide-8 helps soothe and diminish sensitivity. Delivered in a generous 150ml size at R599, this serum provides practical, daily skincare support.
