Because facial liposuction is a very mature technology, the effect is very obvious, and it is equipped with advanced liposuction equipment, which can accurately act on subcutaneous fat layer, and will not interact with facial skin, blood vessels and other tissues, and will not damage facial blood vessels, nerves and other tissues, so it will not affect facial expression. It won't be stiff when you laugh.
