In candidates over 45 years old, the main problems of the face are centered in the lower and middle parts. Sagging and drooping leads to fat accumulation, aggravation of lines, blurring of the jawline, appearance of marionette lines, and a clear sense of sagging and aging of the entire face, when the impact of sagging is much greater than wrinkles. Loose sagging leads to the appearance of decrepit lines and marionette lines filler can not solve the problem. The reason for this is that: This simple filling not only fills in the atrophied tissue, but also improperly fills in the sagging skin that should have been partially removed, thus making some older candidates look like balloons. In this case, it is necessary to lift and reset the sagging tissues, and an important step is the excision of the loose skin. It is unlikely to obtain a natural and long-lasting lifting effect without dealing with the excess skin, and simple fillers cannot achieve this purpose. We must face the main problem of sagging skin and consider face lift surgery to perform extensive subcutaneous peeling to lift, reset and fix the sagging tissue in a youthful position, thus improving the situation of decrepit lines and marionette lines.
