Hormone changes After puberty, hormone levels in women's bodies will change, which may lead to increased melanin deposition on the labia, which darkens the color of the labia. 2. Normal aging process With the increase of age, the skin of all parts of the body will gradually appear pigmentation, labia is no exception.3. Friction Long-term friction, such as wearing tight clothing or frequent sex life, may lead to skin irritation of labia, which in turn causes melanin deposition. 4. Changes in hormone levels during pregnancy and childbirth may cause labia color to darken. Labia may be stretched and rubbed during childbirth, which may also affect their color. 5. Genetic factors Genetic differences between individuals may also cause labia color to vary.
