40 large sized hydrocolloid pimple patches (12mm) formulated with key breakout fighting ingredients including: Ascorbic Acid to correct post breakout pigmentation, Tea Tree Oil to reduces redness and swelling, Niacinamide to soothe damaged skin and Salicylic Acid to remove congestion. Hydrocolloid pimple patches gently absorb excess fluids, like pus and oil, from your pimple while also protecting the wound. They are your perfect partner for preventing scarring and speeding up healing time by making sure you stick instead of pick. Hydrocolloid patches are made from a moisture-absorbing material that's been used for decades in the medical community to help with wound healing. The material gently absorbs excess fluids, like pus and oil, from your pimple while also protecting the wound. By allowing a pimple to heal in a somewhat "sterile" environment, which is key for preventing scarring and speeding up healing time, you'll be left with a flatter, less inflamed pimple by the time you take it off.
