Lip contouring is performed under local anesthesia. An anesthetic in the form of a cream is applied to the skin of the lips and left for 20 minutes, after which the dermatologist-cosmetologist injects a preparation based on hyaluronic acid into the lips using a small thin needle. The places and number of injections are determined by the doctor depending on the goal of the correction (elimination of asymmetry, increase in volume or change in the shape of the lips). During one contour plastic session, the doctor injects no more than one ml of filler. The duration of one procedure does not exceed 15 minutes. A course of several procedures may be required to achieve the desired effect.
