Dermal fillers essentially add volume to facial skin in order to reduce the appearance of lines, wrinkles and hollows. Dermal fillers are used to outline and enhance lips, soften fine or deep wrinkles such as laugh lines or lip lines, and to fill some facial hollows. A local anaesthetic is injected prior to the treatment. The fillers used are very safe and are gradually metabolized by the body. Hyaluronic Dermal Fillers are also completely reversible.
