Thick lip problems often need to be corrected through thick lip thinning surgery. Choosing thick lip thinning surgery involves resection at the junction of the red lip skin and mucous membrane of the upper and lower lips, in a fusiform or zigzag shape depending on the lip thickness. A strip of oral mucosa and muscles are then directly drawn and sutured to make the thick lips thinner, and the stitches are removed in 5-7 days. The surgical incision scar is hidden in the mouth, and the effect is ideal. The lip shape after surgery is naturally harmonious and beautiful.
