COSRX The 6 Peptide Skin Booster Serum 150ml

Elevate your skincare routine with COSRX’s lightweight and hydrating 6 Peptide Skin Booster Serum, crafted to be your first-step toner-serum hybrid that prepares and enhances everything that follows.

• Multi-targeted peptide complex
  Packed with six potent peptides, each delivering a distinct benefit:

  • SH-Polypeptide-121 – supports collagen for firm, plump skin

  • Copper Tripeptide-1 – refines texture and overall smoothness

  • Dipeptide Diaminobutyroyl Benzylamide Diacetate – regulates excess sebum and minimizes pore appearance

  • Oligopeptide-68 – brightens and evens out skin tone

  • Palmitoyl Tripeptide-8 – calms irritation and reinforces barrier protection

  • Acetyl Hexapeptide-8 – softens fine lines and enhances skin firmness

• Light, toner-like texture
  With its ultra-light, non-sticky consistency, this serum applies like a hydrating mist—absorbing quickly while priming skin for seamless layering with stronger actives like vitamin C, retinol, or niacinamide.

• Multi-benefit formulation
  This all-in-one booster targets core skin concerns—pores, oiliness, hydration, elasticity, texture, tone, and sensitivity—making it ideal for those tackling multiple issues in one streamlined step.

• Gentle yet powerful
  Suitable for all skin types, including sensitive skin, thanks to soothing ingredients like niacinamide and allantoin, plus the barrier-calming peptides.

• Scientifically moisturising
  Its humectant-rich formulation—anchored by glycerin and pentylene glycol—delivers effective hydration without heaviness, making it especially appealing for oily or combination skin types.

• Visible results and rave reviews
  Users praise its glow-boosting, firming, and texture-refining effects—many noting improvements within just a few weeks.

• Great value in volume
  Comes in a generous 150 mL (5.07 fl oz) bottle, offering ample product for daily use at an accessible price.
