The labia minora of women has various shapes, about 4-5 cm long and 0.5- 1.0 cm wide, with natural and beautiful curves. Some women's labia minora is over-enlarged, which not only causes ugly appearance and lack of aesthetic feeling, but also causes some local discomfort, such as pudendal pain caused by the friction between labia minora and underwear when urinating, walking and riding a bicycle, and inconvenience or pain caused by being brought into vagina during sexual intercourse. In addition, the adhesion, deformity or obvious asymmetry of labia minora need surgical plastic surgery. Generally, labiaplasty only needs to remove most of the labia minora tissue under local anesthesia, so that the incision line is located outside the labia minora and sutured. For cases of basal hypertrophy, single pedicle mucosal flap can also be used to repair. At present, there is a technology to bleach labia with drugs or tattoos.
