How is vulva pruritus blackened to return a responsibility?

First: genetic reasons: it is genetic factors that determine the primary color of nipples, labia major and labia minor. Young women without pregnancy and childbearing experience are born with dark labia. It is impolite to think that she has been "played".

Second: too frequent sex life causes: during sex life, labia is repeatedly stimulated by external friction for a long time, so that local pigmentation increases, and its color will gradually deepen with the migration of time. This is a normal physiological phenomenon. At the same time, the melanin of hormone during sexual stimulation will also make labia black.

Third: normal pigmentation: female pudendal color is affected by its own melanin precipitation, which is also related to female hormones. The shade of this color varies from person to person and is related to the amount of pigment. Born with white skin, women will be slightly pink, born with black skin, pudendal pigment will be deeper.
