Acnemy's hydrocolloid patches act as a protective layer, helping to absorb the grease and dirt from the pimple, while protecting the imperfections, thus speeding up the disappearance process. In addition, it avoids the temptation to touch it and make it worse. How does Zitproof® Spot work ? Its base with hydrocolloid technology creates an environment that offers optimal conditions to help speed up healing, as well as reduce swelling and redness. In addition, we have impregnated each of the patches with Salicylic Acid, Tea Tree and Centella Asiatica to prevent the appearance of new pimples and help calm redness and swelling. To treat more than one pimple at a time in the same area, you can use Zitproof® Multizits .
