The main method of thinning lips is thick lip correction, which can also be called lip thinning surgery and thick lip trimming. Thick Lip Correction involves cutting off a strip of oral mucosa and muscle in a shuttle or serrated shape at the junction of the skin and mucosa of the red lips of the upper and lower lips, depending on the degree of thickness of the lips, and then pulling together and closing the surgical incision to make the thick lips thinner. The effect of thick lip correction can generally be maintained for a long time, and because the incision is made inside the mouth and lips, there are fewer artificial traces. However, there are risks of lipstick scarring, bilateral asymmetry of the lipstick mucosa, excessive removal of the lipstick mucosa, and insufficient removal of the lipstick mucosa. It is recommended that patients go to a regular hospital, fully communicate with the surgeon about the surgery before the operation, and choose whether to undergo thick lip correction with discretion and caution.
