This issue requires specific analysis of specific problems. If you are obese of the whole body, fat face, fat stomach, fat thighs and calves, medical beauty side should not be considered first, go to exercise and fitness as well as less meals and diet first. If the whole body is thin, only the lower jaw part of obesity, then you can consider liposuction, fiber optic lipolysis or diamond sculpture and other ways to treat. If you have a large area of obesity in the neck, liposuction in the neck is not recommended. Because on the outside of the neck, there is a relatively shallow blood vessel called the external jugular vein. It is relatively thick in shape and may bleed more if there is an injury afterwards. As a doctor, you must consider the choice of approach on a case-by-case basis. If you have deep neck lines, you can treat the raised area with fiber optic lipolysis and fill the depressed part with fat gel, so that the neck lines will be relatively improved. If the neck is saggy and obese, you can also consider doing diamond sculpture or fiber optic lipolysis, and at the same time do neck lift with facelift, the effect is also very good.
