Generally, the amount of fat that can be sucked out of the cheeks is 10 ~ 30ml. Liposuction should follow the principle of small amount and multiple times. Less attraction, less trauma, quick recovery, less pain and no need for general anesthesia. On the contrary, large-scale liposuction surgery is traumatic, painful and slow to recover, and requires a lot of anesthetic drugs, which increases the risk of anesthesia accidents. Generally speaking, no more than 4 servings at a time. However, those medical institutions that claim to be able to extract a large amount of fat, and the extraction site is not limited, should be carefully selected.
