Why do labia turn black?

The reproductive organs of adolescent girls have just developed, and pubic hair grows at this time. Because they have not yet been affected by various sexual activities, their genitals are pink and the pubic hair is not too dark, but some of the hair is black. However, with the frequency of sexual life and the extension of time, the labia will turn black and the color of the pubic hair will become darker.

"Because some cleaning liquids are not good, it seems that many cleaning liquids are corrosive" and so on. These statements are funny, but not scientific. In fact, the darkening of female labia usually does not rule out the following reasons:

Caused by too frequent sexual intercourse: During sexual intercourse, the labia majora is repeatedly stimulated by external friction for a long time, resulting in increased local pigmentation. The color will become darker over time. This is a normal physiological phenomenon. At the same time, the melanin produced by hormones during sexual stimulation will also turn the labia majora into a dark color.

The depth of this color varies from person to person and is related to the amount of pigment in the individual. Women who are born with fair skin will have a slightly pink tint, while women who are born with darker skin will have darker genital pigmentation.
