The "Everything-at-Once" Primer

COSRX The 6 Peptide Skin Booster Serum is the ultimate multi-tasking "first-step" serum. By combining six different peptides, it acts as a total skin coordinator, targeting elasticity, texture, pores, and radiance simultaneously. Its watery, lightweight texture is designed to be layered, prepping your skin to absorb the rest of your routine more effectively.

Why it’s a Real Gem: It’s a "Routine Turbo-Charger." Instead of picking just one skin concern, this serum hits the Pro-Filter mark by addressing them all. It’s a Popular, but Proven favorite because it feels weightless like a toner but delivers the cumulative power of a high-end treatment, leaving your face feeling bouncy and "pre-plumped."

Best For: The "Efficiency Minimalist." Perfect for anyone who wants to simplify their routine with one "booster" that makes every other product work twice as hard.

Key Ingredients

6-Peptide Complex A high-performance blend of six peptides (including SH-Polypeptide-121 and Copper Tripeptide-1) that targets everything from collagen production to pore tightening for a complete skin reset. Niacinamide (Vitamin B3) Regulates sebum production and brightens the complexion, helping minimise the appearance of pores for smoother texture. Hyaluronic Acid and Allantoin A hydration-and-soothing duo that saturates the skin with moisture while calming surface sensitivity for instant comfort. Amino Acids and NMF (Natural Moisturizing Factors) Skin-identical nutrients that reinforce the moisture barrier and improve the natural ability of the skin to retain water for lasting hydration.

How to Use

After cleansing, apply 2–3 pumps as the very first step of your routine (it acts as a "booster toner"). Pat gently into the face and neck until absorbed. Follow immediately with your specific treatment serums (Vitamin C, Retinol, Snail Mucin, etc.). When: AM & PM, daily. Actives tip: This is the ultimate "skincare accelerator." If you find Vitamin C or Retinol too irritating, apply this booster first. The peptides and calming agents create a "buffer" that allows the potent actives to work more deeply while significantly reducing the risk of redness or stinging.
