For a more permanent treatment most people opt for grafting,also known as fat transfer or fat injections. the procedure involves using fat harvested from the patient's stomach or thighs via liposuction and using it to fill out hollowed cheeks and extra volume. prior to transplantation, around half of the fat is processed to enrich the stem cell content. this enrichment process is carried out to improve the prospects for the fat graft. so, the good news is that you do have treatment options when a loss of mid-face volume impacts your appearance.
