Liposuction surgery is generally recommended to wear shapewear for at least 2 months after surgery. Shapewear according to ergonomic principles of three-dimensional cut material, more in line with the characteristics of the human body structure, adjusting the distribution of body fat, shaping a beautiful curve. The main effects are as follows. (1) Plasticizing effect: the continuous pressure has a plasticizing effect on the fat tissue, which is also conducive to the uniform distribution of the fat particles remaining in the suctioned area. We have observed in the clinic that if the bandage is not uniform, fat accumulation can occur in the place where the bandage is looser, resulting in uneven skin. (2) Fixation effect: The elastic garment can fight against gravity and fix the skin fat layer in the correct position. After a period of time, the skin fat layer can be adhered to the deep fat in the correct position, avoiding the skin flap from loosening and sagging, forming golf bag-like deformity. (3) Pressure chasing effect: it can reduce bleeding and tissue edema, avoid local accumulation of exudate and formation of hematoma or seroma, and speed up the postoperative recovery time. The pressure of elastic compression garment should be moderate, and the size should play a role in molding and fixation. However, too much pressure can easily lead to phlebitis, venous thrombosis and other complications. For patients after lipofilling, it is generally recommended to wear body shaping garments for at least 3 months after liposuction. However, the filled area is not required to use headgear and other compression, so as not to affect the fat shaping and reduce the survival rate.
