Dermatologist Note
Hydrocolloid patches work by absorbing wound exudate (fluid from a blemish) and creating a moist healing environment. Studies show moist wound healing accelerates repair by up to 50% compared to leaving blemishes exposed. The occlusive seal also prevents picking, which is the primary cause of post-inflammatory hyperpigmentation (PIH) from acne.
Based on published clinical literature and dermatological research.
