The skin of the pubic area is roughly the same as the skin of other parts, except that the density of blood vessels and nerves is higher, so it is more sensitive to external stimulation. What is mentioned in the book or our clinical observation Yes, the main factors that affect skin color are heredity, race, age, and hormonal changes in the body. They have nothing to do with the amount of sexual activity. When you get older or go through menopause, the melanin produced by aging skin will decrease. The color will also become lighter, but this is not due to less sex. Free radicals are also produced during exercise, but they are systemic, and the body's reaction during sex is not limited to the vagina. What's more, the body also has a good repair function to offset free radicals.

In fact, the color of a woman’s vagina is affected by her own melanin deposition, and this pigmentation is also related to female hormones. That is to say, the vagina of a woman has not developed since childhood, so the entire external genitalia is covered by the labia majora, and the skin of the vagina is the same color as the skin of other parts. After the female growth period, due to the influence of hormones, hair will grow on the female perineum, and the labia minora will be more prominent than the labia majora. At this time, the color of the vagina will also begin to deepen.

Of course, the degree of deepening varies from person to person and is related to the amount of pigment in one’s own body. For example, the pigment of white people is lighter, so the probability of pink appears is higher; while the pigment of Asians is slightly darker, so the color of this part is usually brown. Women with naturally fair skin will also be slightly pink, and women with naturally darker skin will have darker pubic pigmentation.
