According to Professor Sun Baoshan, a plastic surgeon in Shanghai Ninth People's Hospital, he has to do dozens of cosmetic surgery every month. Because many women with square faces want to change into oval faces, including men with baby faces, they also want to give themselves more masculinity. It must be a little traumatic to cut off the cheekbones with a chainsaw and rebuild them with steel wires and plates during the operation. It usually takes three months to get back to normal after the operation. So from the doctor's point of view, they think that people with serious facial defects can consider doing this operation, and normal people had better give up this idea.
