COSRX – Pimple Master Acne Patch 24pcs

A set of hydrocolloid acne patches designed to protect pimples and speed up healing by absorbing excess fluid (pus, oil, and impurities). It creates a moist healing environment that helps reduce inflammation, prevents picking, and lowers the risk of scarring.

The pack contains 24 patches in 3 sizes (small, medium, large) for different acne types and areas.

Key Active Ingredients

  • Hydrocolloid (A.D.F Hydrocolloid Dressing) – absorbs pus and oil, maintains moisture, and supports faster healing of pimples.
  • Polyisobutylene / Styrene Isoprene Styrene / Polyurethane Film – forms the adhesive and protective patch structure that seals the skin.
  • Cellulose Gum / Petroleum Resin / Liquid Paraffin – supports absorption and patch stability.

(Note: This product does NOT contain active acne drugs like salicylic acid—its effect is purely physical healing protection.)

Environmental Commitment

  • Minimal skincare formulation (no added actives or fragrances)
  • Designed for single-use medical-grade wound protection
  • Packaging should be disposed of according to local recycling rules
  • No official sustainability certification publicly stated by the brand
