What is COSRX The 6 Peptide Skin Booster Serum?

The COSRX The 6 Peptide Skin Booster Serum is a comprehensive anti-aging and skin-firmness serum formulated with 6 different bioactive peptides in a generous 150ml format. Peptides are short amino acid chains that act as signalling molecules in the skin — triggering specific biological responses including collagen synthesis, elastin production, muscle-relaxing action, and barrier strengthening. For Pakistani skin beginning to show signs of premature aging from UV exposure, pollution, and stress, a well-formulated multi-peptide serum provides one of the most evidence-backed approaches to skin renewal.

Key Ingredients & Benefits

The serum contains 6 distinct peptides, each targeting different aspects of skin aging: Acetyl Hexapeptide-8 (Argireline) relaxes the repetitive micro-muscle contractions responsible for expression lines, providing a topical 'muscle-relaxing' effect that visibly reduces the depth of expression wrinkles with consistent use. Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 (Matrixyl complex) are among the most clinically studied peptide combinations available, with peer-reviewed research showing they stimulate fibroblast production of collagen I, III, and IV, reducing wrinkle depth by 27–45% over 2 months in clinical trials.

Leuphasyl and Leuphasyl-10 work synergistically with Argireline to enhance muscle-relaxing effects. Copper Tripeptide-1 (GHK-Cu) is one of the most bioactive naturally occurring peptides, promoting wound healing, stimulating collagen and elastin synthesis, and providing potent antioxidant protection. For Pakistani skin dealing with premature photoaging from unprotected UV exposure and oxidative stress from urban pollution, the GHK-Cu component alone provides significant anti-aging and repair benefits. The 150ml bottle size makes this one of the most economical per-ml peptide serums available from a premium Korean brand.

How to Use COSRX The 6 Peptide Skin Booster Serum

Apply after cleansing and toning as your serum step, before moisturiser. Dispense 3–5 drops (or 1–2 pumps), warm between fingertips, and gently press into skin using upward and outward lifting motions (the mechanical lifting motion enhances peptide penetration). Focus on areas of concern — forehead, nasolabial folds, under-eyes, jawline. Use AM and PM for best results. Peptides are stable and compatible with most other ingredients — no timing restrictions. The 150ml size provides approximately 5–6 months of twice-daily use.
