The methods of slimming the face of boys and girls are largely the same, and are generally divided into two categories: first, if the face is large and square due to excessive bite muscle, then Botox can be injected, Botox by blocking the nerve-muscle junction, so that the muscle loses nerve nutrition and atrophy, the face is slimmed down. But also note that if the facial fat is too thin, after the injection of Botox, the face quickly become smaller, will look very unnatural, at this time you can inject hyaluronic acid, filling part of the face, which will look more beautiful and natural; if the facial fat is too thick, then after the injection of Botox muscle atrophy, facial slimming effect will not be very obvious. Secondly, if the face is large due to over-square bones, then Botox injection is useless, at this time, surgery must be done to grind down the bone or cut off some, such as cutting off the jaw angle, so that the face is obviously slimmed down.
