The COSRX 6 Peptide Skin Booster Serum is a multi-functional treatment essence designed to improve elasticity, smooth texture, minimise pores, and boost overall skin health — all in one lightweight layer.

This is more than a serum — it’s a skin booster step.

It helps:

  • Improve elasticity and firmness
  • Smooth uneven texture
  • Minimise the appearance of pores
  • Brighten dull skin
  • Strengthen the skin barrier

It works by prepping your skin, allowing the rest of your products to absorb better and perform more effectively

Key Benefits

  • 6 Peptide Complex – targets firmness, fine lines, pores, and overall skin quality
  • Niacinamide – brightens, evens tone, and improves skin clarity
  • Hyaluronic Acid – deeply hydrates and plumps the skin
  • Adenosine – supports anti-ageing and smooths fine lines
  • Improves elasticity and firmness
  • Smooths uneven texture and refines pores
  • Brightens dull skin and strengthens the skin barrier
