Streamline your skincare routine with COSRX’s The 6 Peptide Skin Booster Serum, a dermatologically tested formula designed to address multiple skin concerns! Powered by 6 potent Peptides (short chains of amino acids that accelerate skin collagen production), this serum enhances firmness, refines texture, minimises fine lines, regulates sebum, and balances skin tone! Each Peptide brings unique benefits, from boosting collagen and brightening, to pore care and soothing sensitivity. Its lightweight, non-sticky texture absorbs effortlessly, leaving your skin smooth, soft, and hydrated after every application. Perfect for anyone seeking a comprehensive solution to achieve a radiant and rejuvenated complexion, this serum is the ultimate addition to any pared-down skincare regimen!

  • 6 Peptides: 6 types of Peptides address multiple skin concerns: SH-Polypeptide-121 boosts collagen production, plumping up the skin; Copper Tripeptide-1 softens and improves skin texture; Dipeptide Diaminobutyroyl Benzylamide Diacetate removes excess Sebum and provides pore care; Oligopeptide-68 brightens skin tone; Palmitoyl Tripeptide-8 soothes inflammation and decreases skin sensitivity; finally, Acetyl Hexapeptide-8 helps to soften fine lines and boost skin firmness.
  • Niacinamide: A water-soluble vitamin, Niacinamide works with the natural substances of the skin to help even out skin tone, improve dullness, and bolster weakened skin barriers.
  • Sodium Hyaluronate: A derivative of Hyaluronic Acid, Sodium Hyaluronate helps to pull moisture into your skin for a plumping effect, while also reducing inflammation.
