Why do people have black moles?

Although it is common to have moles on the skin, why do people get moles? This is a question that confuses many people. In fact, moles are very common, and there are many reasons for the formation of moles. The main reasons are: moles caused by congenital genetic factors; endocrine disorders; lack of protection against ultraviolet rays; and finally, bad living habits and psychological factors, which are all causes of moles.

1. Congenital genetic factors

Due to genetic reasons, some people are more likely to produce pigments than the average person, and are therefore more likely to develop moles. There is also autosomal inheritance, with rice-sized spots appearing that are heavier in spring and summer and lighter in autumn and winter. This situation is more likely to occur in girls over 5 years old.

2. Endocrine disorders

The function of the body's endocrine system also affects the formation of moles. Changes in hormones during puberty, women's menstrual period, or pregnancy may cause endocrine disorders, and the possibility of forming moles during this period increases.

3. Excessive exposure to ultraviolet rays

Exposing the skin to strong ultraviolet rays for a long time can easily lead to the formation of melanin and pigment deposition, which in turn leads to the formation of moles.

And if you are exposed to strong ultraviolet rays for a long time, the invisible or light moles on your face will gradually turn darker and all of them will appear. There will be more and more moles on your face, so you must wear sunscreen when going out.

4. Bad living habits

Being under great stress in life, or suffering from long-term lack of sleep or poor sleep quality can cause damage to skin function and the formation of moles. Secondly, it is because of incorrect eating habits and long-term overeating, which causes the heat in the body to continue to rise and toxins in the body to continue to accumulate. If this continues for a long time, it will cause black moles to grow on the skin.

5. Influence of neurological factors

People who are depressed or emotionally unstable for a long time are also prone to the formation of moles. When the emotions are unstable, the melanocyte-stimulating hormone secreted by the pituitary gland will increase, which will lead to an increase in melanin and easily form pigment deposits to form spots, moles, etc.
