Liposuction, also known as liposuction, is a method to lose weight by using instruments similar to uterine curettage to pierce the subcutaneous fat layer through a small incision in the skin and scrape off the fat, and then using the suction of negative pressure to suck out the fat fragments through the catheter. Because this method can only suck out subcutaneous fat, and it is limited to a certain part of subcutaneous fat, it has little effect on losing weight, but it has a significant effect on improving the appearance of a certain part. Therefore, it is only suitable for the uplift of a certain part caused by simple obesity, and the skin elasticity is good. Satisfactory results can only be obtained if the local skin has good retraction elasticity after liposuction. So liposuction is suitable for body shaping.
