Juvederm is a dermal filler made of hyaluronic acid which is a natural substance found in the human body. It is injected into patients to improve the appearance of facial wrinkles and age lines by adding volume to plump the skin. Juvederm can be injected into any area of the face including the mouth, forehead and nose to contour the face and improve the appearance of lines and scars. It can also be used to enhance the shape and size of the lips. The entire process takes about 15 minutes. The doctor numbs the area to be treated before injecting a needle into the designated area. The amount used depends on the results desired by the patient.
