Ectropion and darkening of the external labia is considered to be related to pigmentation, sexual stimulation, and degeneration of the reproductive organs. Women in their reproductive years have higher estrogen, and hormonal stimulation will lead to pigmentation of the vulva to form darker skin color, such as black dark gray, etc. With the increase in the number of times of sexual life, repeated friction will aggravate the color of the vulva, and will also lead to local skin relaxation, which is a normal physiological phenomenon. In addition, as we age, the skin of all parts of the body begins to loosen and sag, and the vulvar labia are no exception, and will become inelastic. Women who have given birth, especially those who have given birth twice or more, have experienced significant hormonal fluctuations in their bodies, and their body shape has been affected by localized changes in their reproductive organ areas. Don’t be overly nervous about vulvar labia ectropion and blackness, if there are abnormalities, such as pain, burning, itching, etc., you should go to the hospital in time to communicate with the doctor and follow the doctor’s instructions to deal with the treatment, do not delay the condition.
