From an aesthetic point of view, a woman's upper lip is slightly thinner and slightly upturned than her lower lip, and the corners of her mouth are slightly upturned, which is charming. A beautiful mouth can show women's personality and emotions, and also attract the attention of the opposite sex. However, there are always some women who suffer from poor lip shape. Among them, the most common is that the mouth is too generous. It is generally believed that in the relaxed state, when the upper and lower lips are slightly closed by more than 2cm, the upper and lower lips are thick lips. If it is a thick mouth deformity, it can be corrected by cosmetic surgery. That is, an incision is designed at the inner edge or more inner side of the red lip, which is in the shape of a transverse shuttle, with both ends extending to the cheek. The incision between lip bead and labial frenum in the center of the upper lip is not made, and the obvious lip bead is reserved. The width of lip tissue should be carefully measured in consultation with patients before operation, so as not to cause the red lip to be too thin and the lip arch edge to contract inward. Generally, it takes 1-2 weeks to recover if the suture is removed after one week of lip surgery.
