The application of fillers containing hyaluronic acid is one of the most requested procedures in the field of corrective dermatology. The treatment using the hyaluronic acid, a substance naturally occurring in the human body, produces immediate and natural results. It aims to model sagging facial contours, correct wrinkles and reshape lips. The length of the procedure ranges between a quarter to three-quarters of an hour. It is performed under local numbing of treated parts of the face. The client can leave the clinic immediately. Swelling, if it occurs, will disappear after two to five days. The effect of the application of hyaluronic acid persists for about a year.
