The normal labia of more women is about 4-5cm long and 0.5- 1.0cm wide, and the labia curve is natural and beautiful. Young women's labia are generally pink, but with the increase of age and sexual life, the color of labia will gradually deepen, making labia lose its original pink, so labia bleaching surgery was born. According to experts, labia minora surgery is a small gynecological plastic surgery, which does not require hospitalization and does not affect normal life. Generally, a special needle is used to stab the pigment into the dermis, and the operation can be successful for many years without turning black. The operation of reddening labia is a good prescription for some female friends with dark labia. Some women's labia minora is over-developed beyond the normal range, which is called labia minora hypertrophy. Some people with labia minora hypertrophy have no symptoms, but some people often have some local discomfort, so it is necessary to do labia minora bleaching surgery.
