It is used to treat still wrinkles or to give volume to the thinned tissues (lip augmentation). The most common application areas are the lips, the frown lines that cannot be eliminated by botox, the lines extending from the nasal edges to the lip corners (nasolabial line), the lines extending from the lip edge to the chin (marionette line), grooves formed by various causes, and sometimes the genital area.
FDA-approved hyaluronic acid is preferred as the filler material. It is administered under local anaesthesia. A little oedema may occur in the application area. This recovers within 1-3 days. After 4-6 months, it disappears by being absorbed by the body.
