Muscle relaxants are used to treat wrinkles and lines caused by repeated muscle movement, such as
smile lines and forehead creases. They work by temporarily weakening the underlying muscles. Dermal
fillers are used to plump up the skin by adding volume. They may be used to fill in wrinkles caused by
sagging skin, to restore volume lost to the ageing process, or to enhance areas of the face such as the
lips and cheeks.
