After liposuction on the face, it will not cause skin relaxation, because in the process of liposuction, not only fat will be extracted, but also a uniform "scar" will be formed under the skin. When the scar is self-repaired, it will stimulate the proliferation of collagen fibers, thus achieving the effect of firming the skin. Moreover, liposuction surgery will control the treatment level very well. Most people wear hoods after liposuction on the face, also to shape the facial skin. It takes about half a month to a month after liposuction to prevent facial skin from becoming slack. After liposuction, the local wound can be bandaged with pressure and cold compress with ice pack, which is beneficial to the retraction of loose skin after aspiration and plays a role in local shaping.
