The doctor chooses which combination of active substances to use according to the skin’s needs. The application of a numbing cream precedes the treatment which makes it completely painless. The doctor then, injects, using a very thin needle, the chosen substances. At the end of the treatment a special mask is applied to soothe the skin so that the patient can immediately return to his activities. A mild redness is possible to occur which subsides in a few hours. Rarely bruising can occur in the injection area.
