Until recently, most of the surgeons saw the face aging as a problem of excess tissues. Therefore, surgery is designed to remove the “excess” of tissue. However, if you really study the aged face you will realize that much of what we perceive as facial aging has a lot to do with the loss of volume. The face deflates like a balloon losing air, as a grape becomes a raisin, the face loses its force as the same time that skin thins and fat is lost.
There is also another change; the skin of the face is supported to the underlying bone in certain areas by ligaments. In these areas of fixation, there is a particular loss of volume, where we can see the development of deep furrows and wrinkles. That is why currently is understood that the main problem is the loss of volume in the furrow.
It is deducted that the solution is to provide volume. Here is where hyaluronic acid plays its role as the filler product more secublogre and effective.
