The facial regions that have lost volume can be treated with filler replacements. The body’s own fat are usually transferred into the forehead, cheeks and lips. The body usually metabolizes some of the fat but the rate and amount varies according to the technique performed and the patient’s tissue. The process may be repeated. Hyaluronic acid fillers are another filler alternative. Hyaluronic acid fillers slowly dissolve over about 8 months and treatments are repeated. I generally do not use permanent synthetic fillers.
