Upper lip curvature can be corrected by Botox injections, surgical correction and other methods. 1. Botulinum toxin injection: A small amount of Botulinum toxin is injected into the subcutaneous muscle in the place where the warped lips are obvious and want to be corrected. Botulinum toxin is a wrinkle remover, and there are two kinds of commonly used wrinkle remover needles: domestic and imported. However, the effect will disappear after only a few months. 2. Surgical correction: the upper lip can be corrected through surgery. The surgical effect is more lasting, but the audience is narrower, only suitable for patients with a higher upper lip and lower nose. 3. Other methods: The upper lip curvature is considered to be due to the outward tilt of the upper teeth, which can be improved through orthodontics, or it may be due to the protrusion of the maxilla, which can be corrected by orthodontic braces and orthognathic surgery on the jawbone. If you want to correct the phenomenon of upper lip overcurvature, you should consult your doctor in time and actively cooperate with the treatment.
