Before the treatment, skin must be clean and any make up or cosmetics should be removed, preferably using an astringent or facial cleansing lotion and cold water to ensure that pores are not dilated. In order to avoid increased bleeding and swelling at the injection site, it is strongly advised that non steroidal antiinflammatories (Advil, Aspirin), Vitamin E or blood thinners are avoided one week prior to treatment.
