The COSRX Acne Pimple Master Patch primarily uses hydrocolloid (Cellulose Gum)
as its main ingredient, which forms the patch and draws out gunk, plus
other components like Styrene Isoprene Styrene Block Copolymer,
Polyisobutylene, Petroleum Resin, Polyurethane Film, Liquid Paraffin,
and Tetrakis Methane, all creating a moist environment to heal spots and
prevent scarring.Key Ingredient Breakdown:

• Hydrocolloid (Cellulose Gum): The core material that absorbs fluid from pimples, turning white as it works, and protects the wound.
• Styrene Isoprene Styrene Block Copolymer: A synthetic rubber used in the patch's adhesive/structure.
• Polyisobutylene & Petroleum Resin: Help with adhesion and the patch's flexible, protective qualities.
• Polyurethane Film: Forms the thin, clear outer layer of the patch.
• Liquid Paraffin & Tetrakis Methane: Act as plasticizers and stabilizers for the hydrocolloid. 

How it Works:You
apply the patch to a clean, dry blemish; the hydrocolloid material
creates a moist healing environment, drawing out pus and oil while
shielding the spot from dirt and bacteria, thus speeding up healing and
preventing scarring.
