A closed healing environment can promote the proliferation of microvessels and the formation of granulation tissue, thus accelerating wound healing. It can play a role in debridement. On the one hand, hydrocolloids contain endogenous enzymes that can promote the dissolution of fibrin. On the other hand, the closed environment provided by hydrocolloid dressing is beneficial for macrophages to remove necrotic tissue.

Precautions:
Acne patch is not easy to use, mainly for small acne, and the effect of big acne is not obvious. You must wash your face before using the acne patch. If you feel that it can't be torn off, you can use a cotton pad to soak in water and press it around the acne patch, and then tear it off after it becomes soft.
Stick it firmly. Pick out the small bags with white hair at night, squeeze them clean and paste them. When I opened it the next day, I could clearly see that the bag was flat and white pus was sucked out. Really super easy to use. It is necessary for acne, and pus can be sucked out slowly. Then the hard one next to the acne will slowly soften and stop the pain. Acne will recover soon.
