Liposuction is generally only suitable for people aged 18 ~ 55 who have limited fat accumulation, but have no organic cardiopulmonary disease, no serious drug allergy history and no coagulation disorder. The effect of professional liposuction on waist and abdomen is more reliable than that of exercise, diet adjustment and drug weight loss, and it is not easy to recur. This is because the total number of fat cells in adults is certain. After exercise, diet adjustment, lifestyle change, drugs and other weight loss methods can not reduce the number of fat cells, but only reduce the volume of fat cells to achieve the purpose of weight loss. Generally, highly skilled doctors don't leave scars.
