Why are my neck and armpits dark?

Everyone's skin is different. Some people have fair skin, while others have darker skin. This has a lot to do with one's own physical constitution. If you find that your neck and armpits are darker than other parts of the body. This is mainly related to genetic reasons and pigmentation deposition. If you have frequent sexual life, this situation may occur. You should choose different treatment methods according to your own situation. So what is the specific reason?

The following reasons cannot be ruled out:

1. Genetic reasons;

2. Caused by too frequent sexual life;

3. Normal pigmentation. That is to say, sexual intercourse causes the labia to darken, including the vaginal opening and the inner and outer labia. During sexual intercourse, the labia is repeatedly stimulated by external friction for a long time, resulting in increased local pigmentation. Its color will become darker over time. This is a normal physiological phenomenon.

At the same time, the melanin produced by sexually stimulating hormones can also turn the labia into a dark color.

Because the skin on the human body is not all the same color, the skin color of the so-called pubic areas such as the armpits, groin, and vulva is darker than other places. This is normal. For some people the difference is minor, for others it is more obvious.

If these pubic areas have ever been inflamed or have eczema, it will cause pigmentation in that area of ​​the skin, making the skin tone darker.

If you notice unusually heavy dark pigmentation in your armpits and you are overweight or obese, or have a family history of diabetes, you may want to get your blood sugar levels checked.
