Common Questions

  • Who is the COSRX The 6 Peptide Skin Booster Serum suitable for? This serum is designed for all skin types: It is particularly beneficial for those looking to address multiple concerns like fine lines, large pores, and loss of firmness with a single product.
  • Why should I choose a booster serum over a regular serum? The COSRX Booster acts as an "amplifier": Unlike standard serums, it focuses on improving the skin's overall receptivity, making every other product in your routine significantly more effective.
  • Can I use this product with Vitamin C or Retinol? Yes: The gentle peptide formula is designed to be compatible with other active ingredients, providing a soothing base that helps prevent irritation from stronger treatments.
  • Does this serum leave a greasy residue on oily skin? The formula is remarkably lightweight: It features a water-like consistency that disappears into the skin, leaving it feeling smooth and hydrated rather than oily or heavy.
  • How quickly will I see results from using peptides? You will notice immediate hydration and a smoother texture: With consistent daily use, the six-peptide blend works to visibly firm and refine the skin’s appearance over several weeks.
