Sudden Fat Loss in Cheeks - What Happened?

Facial atrophy is very uncommon, but it can be treated with facial fat transplantation or grafting.  Recently this technique has gained increased attention because of the advances with water-assisted liposuction (Body-Jet) for fat harvesting.  The advantage of Body-Jet is that the fat cells aren't damaged in the process of being removed and, therefore, they have a higher survival rate than fat cells transferred with other techniques.  Because these fat cells  also contain stem-cells, this may provide an extra benefit for treating facial atrophy.  

hi Demoizelle ,In the presence of perfect health fat loss in the face is a natural occurrence which accompanies the aging process, and sometimes makes faces look less attractive.As others have mentioned, fat grafting may help but takes many treatments and may not look natural especially if there is a later significant weight gain.Midface cheek implants are an excellent permanent solution but can also be removed without harm if they become unwanted.It is unusual to lose facial "baby fat" at your age but exercise and weight loss can certainly be a natural cause Dr Edward o Terino ,

I have seen a similar instance in  a 24 year old girl before. It is described as Idiopathic adipose distrophy  and no definite causes has  been  attributed in a otherwise healthy person. It can happen to fat in other parts of the body also. Ihe process may be atrophy (wasting) or hypertohy(increase). We are learning more about adipose tissue and some of the findings are surprising. There is a slim chance the process my reverse or you may opt for fat transplantation with adult stem cell to restore the contour.
