Why are girls' bottoms black?

A woman’s skin down there should be tender (such as the vulva), but why do some people have dark skin down there? There are many interesting speculations about the darkening of women's private parts, such as "women's labia become darker because of friction caused by walking, which causes the labia to turn black" and "some lotions are not very good, and it seems that many lotions are corrosive." These names are funny, but they are not scientifically based. In fact, the darkening of women's labia usually does not exclude the following reasons:

Genetic reasons: The color of the nipples, labia majora and labia majora is determined by genetic factors. For young women who have no experience of pregnancy or childbirth, even if the vulva becomes dark, it is rare. If you think she has been "played too hard", it would be very rude.

Excessive sexual intercourse often causes: During sexual intercourse, the vulva is repeatedly stimulated by friction from outsiders for a long time, resulting in increased local pigmentation, and its color will begin to darken over time. This is a normal physiological phenomenon. At the same time, the pigment of male hormones during sexual excitement will also make the vulva darker.

Normal pigmentation: The color of the female genitals is affected by the body's own melanin deposition, which is also related to female hormones. The intensity of this color varies from person to person and is related to the amount of melanin in the individual. Women who are born with fair skin will have a slightly pinkish tint, while women who are born with darker skin will have darker melanin in their private parts.

If you want to return to the "watery and tender" period of a beautiful girl, you can also try some products that can "whiten the skin" of your private parts, but you need to use them with caution. After all, safety and health are the main prerequisites for women to care for their private parts. Remember not to use drugs blindly.
