There is a certain amount of fat in the buttocks, especially in women, and the buttocks will be fuller. Hip is one of the parts of the human body that are prone to fat accumulation. Too much fat deposition is harmful to physical beauty. Hu Qingxu introduced that the location and quantity of hip fat deposition are different. According to the different deposition position and hip shape, it can be divided into upper hip type, and the fat is concentrated on the hip, which is more prominent; Hip-side type, fat is concentrated on both sides of the buttocks, so that the buttocks protrude to both sides; Rear hip type, which makes the rear of the hip stand out obviously; Balanced type, with uniform distribution of hip deposits. No matter what kind of fat is deposited on the buttocks, it is an abnormal posture and lacks aesthetic feeling.

Expansive liposuction is an effective method to reduce local fat accumulation and a new technique in cosmetic surgery. Its principle is to use negative pressure to attract excess fat under local skin after local injection of dilating anesthetic solution, so as to shape a perfect body shape and achieve cosmetic effect. According to the different types of hip fat deposition and different plastic needs, the amount of fat absorbed by different parts is also different. Because the number of fat cells in adults no longer increases, obesity is caused by the increase of fat cells. After liposuction, the number of cells decreases, thus achieving the effect of local shaping, which is not easy to rebound.

The shape sculpture of buttocks is carried out by liposuction of buttocks. When the buttocks droop, part of the fat at the lower part of the buttocks should be sucked out, and the lower part of the buttocks should be made into a ball shape to expose the gluteal groove. The gourd buttock should suck out the subcutaneous fat at the joint between the outer buttock area and the side waist, so that the upper part of the buttock is spherical, forming a hip-lifting and waist-bending. For big fat buttocks, the whole buttocks should be liposuction and thinned, and the hip circumference should be reduced by a circle, and the hip circumference should be reduced to a range suitable for your height. As for the flat and wide buttocks, autologous fat transplantation or other tissue substitutes can be considered to enrich the buttocks.
