The main component of the mouth shape is the shape of the lips. If the shape of the lips is graceful, with a degree of opening and closing, and a natural curvature, the mouth shape will definitely look good. If the lips are incompatible with each other, it will inevitably affect the beauty of the mouth shape, and then affect the entire beautiful structure of the two parts. Well, experts said that with modern plastic surgery technology, lip plastic surgery is to remove a strip of oral mucosa and muscle in a fusiform or zigzag shape depending on the thickness of the lips at the junction of the skin and mucous membrane of the upper and lower lips, and then directly pull the incisions together and suture them. Thick lips become thinner. Lip thinning surgery takes a short time. Lips can be made thinner by removing a strip of mucous membrane and performing plastic surgery and suturing.
