Shortening is a plastic surgery that is not often used on the face, but it is a better method for people with really long faces. If only the middle sulcus is too long, it can be corrected by injection. If the white lip is too long, you can choose to shorten the middle groove under the nostril. During the operation, the redundant tissue was not removed, but a tissue flap was formed to remove the epidermis and sent to the subcutaneous sulcus. Because people have a great influence on people's health, we should pay more attention to some things when accepting people's shortening surgery, so as to have better protection for health and safety.
