If injection technology is used, it usually takes two to three months to take effect, and it will rebound slowly after eight months, which requires long-term injection to maintain.

If liposuction technology is used, the effect will gradually appear after one month, and the duration will be longer and better.

If bone grinding or osteotomy is used, the methods of grinding cheekbones and mandibles are generally used, which will lead to larger wounds and longer recovery time. The surgical effect is still good.
