The changes of aging in the face are similar to the changes on the back of your hand - the skin becomes thin, looses its elasticity and as the fat is lost, we start to see the veins and tendons.
The loss of fat in the face causes the skin to sag and gives a tired appearance. People who have lost a lot of weight, who are sick or have serious illness such as AIDS will often look very gaunt and old. On the other hand, women who are obese will often have beautiful faces with young looking skin. Injections of your own body fat to the soft tissues of the cheeks and around the eyes can restore a youthful and healthy appearance to many patients.
As we age skin thins out and may form deep creases and lines. By injecting fillers (such as ones with hyaluronic acid - a natural component of skin) either directly into the skin or underneath it, these lines can be dramatically lessened and sometimes even erased. There are many different types of fillers available on the market and each plastic surgeon may have his or her preferences.
Whatever is used, fat injections and fillers around the eyes, lips and to the cheeks can give a refreshed and youthful appearance.
