Plump forehead and cheeks is a sign of youth.
The aging of face begins around age 20 and due to loss of original tissue, the forehead will become flat, the outer cheeks become sunken or the whole face is not as tight as when you were young.
The best way to resolve the loss of tissue is the use of filler, such as hyaluronic acid, radiasse, collagen, autologous fat, etc. Beside autologous fat, other kinds of fillers cannot last long. The advantage of autologous fat is once it achieves stability, it will stay with you forever. Moreover, the fats will not undergo rejection and displacement. However, the key to the results is the technical skills of the physician and the presence of growth factors.
Recent medical studies have shown that the reason the survival rate of fat is low is because the amount of stem cells are around half the amount of original fat. During the surgery, some of the stem cells are lost to the blood while some still remain in the body parts that provide the fat. This is because stem cells usually exist in the arteries. The extracted fats have no arteries therefore the amount of stem cells is surely lesser. These reasons are normally the factors that result in the failure of the surgery.
Stem cells are responsible for the new cells of the arteries and the supply of oxygen and nutrients. They are also responsible for the supply of growth factors for the grafted fat. At the same time, they will convert into fat cells when necessary. If the grafted fat lacks the help of stem cells, the survival rate will be low. Therefore, if the concentration of stem cells in the extracted fat can be increased, this problem will then be solved.
Japanese and Korean researchers found out that, if the extracted fat is split into two parts, one for the extraction of stem cell while the other to be purified and then added to the previous stem cells, the concentration of stem cells in the purified fat will be doubled.
Autologous fat grafting does not help fill the facial imperfections, but also helps in shaping a plump and ideal face structure such as cheek and forehead. The growth factors in the fat can also smoothen the skin’s fine lines, which results in a tighter and more elastic facial skin.
