This is actually a relative issue. If you have a larger weight base and more liposuction and a larger amount of skin after the procedure, there is a risk of loose sagging skin. However, if the contouring is only localized, it will not produce loose sagging skin after the procedure. In the process of liposuction, the traumatized surface of the fat layer will form a scar, and the scar has the effect of contracture. Generally speaking, mild laxity can be flattened by the contracture of the scar, and will not form the laxity and sagging of the liposuction area. If the skin itself is loose, we recommend doing skin tightening treatment at the same time as liposuction. For example, now I often use the diamond sculpture, it is through a dual electrode, dual temperature control instrument, in the liposuction lipolysis at the same time for skin tightening treatment, so that the skin is heated to produce collagen regeneration, which is the same principle as ultrasonic knife, Thermage, but the diamond sculpture belongs to the invasive surgical treatment, for the face of the microfat at the same time accompanied by skin laxity of the applicants, is a very good choice.
