The key point of hip liposuction is to reduce hip circumference, pull up loose and drooping parts, and adjust hip height backwards while reducing hip circumference width. Liposuction on the buttocks can reduce the fat on the upper part of the buttocks, and the curve from the waist to the buttocks looks smoother and smoother, reducing the fat at the root of the thigh and making the thigh look more beautiful and slender, which can kill two birds with one stone. After years of clinical experience, hip liposuction has been quite mature. The incision of liposuction on buttocks is selected at the folds of buttocks and thighs, and small incision is adopted to liposuction evenly. When operating, handle the transition surfaces of adjacent positions to avoid unevenness to the maximum extent. Because the incision has a shadow, it gradually disappears into the folds of the skin over time, which is not easy to see, and the postoperative recovery is fast, which does not affect work and study.
