  • 6 Peptide Complex — What Each One Does — Copper Tripeptide-1 (GHK-Cu): stimulates collagen and elastin synthesis, accelerates barrier repair. Acetyl Hexapeptide-8 (Argireline): relaxes expression lines. Oligopeptide-68: inhibits melanin for brightening and even tone. Dipeptide Diaminobutyroyl Benzylamide Diacetate (Leuphasyl): reduces muscle contraction-related fine lines. SH-Polypeptide-121: skin renewal and regeneration. Palmitoyl Tripeptide-8: calms inflammation and soothes skin. Six different mechanisms in one step.
  • Niacinamide + Adenosine + Acetyl Glucosamine — niacinamide evens skin tone, controls sebum, and supports the barrier. Adenosine improves elasticity and reduces the appearance of fine lines. Acetyl Glucosamine brightens and acts as a HA booster for deeper hydration.
  • Full Amino Acid Profile + NMF Complex — Serine + Alanine + Glycine + Threonine + Arginine + Proline + Glutamic Acid + Lysine provide the complete building blocks of the skin's Natural Moisturizing Factor. Sodium PCA + Sodium Lactate + Betaine are biomimetic humectants that hydrate without heaviness. Sodium Hyaluronate and Dextran add surface and film-forming hydration.
  • First-Step Booster — How to Layer It — use immediately after cleansing, before serums and ampoules. Apply 2–3 pumps and pat gently. Can be layered multiple times to intensify the booster effect. Compatible with Vitamin C, Retinol, Niacinamide, Ceramide, and Snail Mucin. Pairs best with COSRX Snail 96 Essence + COSRX Advanced Snail 92 Cream.

After cleansing, apply 2–3 pumps to face and pat gently until absorbed. Use AM and PM as the first step of your skincare routine. Fragrance-free. 150ml.
