If the pigmentation of the skin is broken on the human body, pigmented spots may appear. They do not itch, they do not hurt, but they bring a lot of problems from an aesthetic point of view. More often such spots are formed in people after forty years, but also they can be observed in young people.
The most common cause is age-related changes, since after forty years cells begin to lose the ability to interrupt production pigment. Also, spots appear due to exposure to sunlight. This is due to the fact that ultraviolet rays damage the melanocytes that produce melanin. For example, when a person applies cologne or toilet water to open parts of the body, the essential oils contained in them can increase the susceptibility of the skin to the sun's rays. As a result, dermatitis is possible, and behind it also pigment spots. Provide increased pigmentation and improper facial care procedures.
Sunlight is most affected by the back of the hands. Over time, there may appear solar lentigo, which is also called "senile" spots. These spots are formed with constant exposure to the sun. During sunburn, these spots merge with the rest of the tanned skin, but when the tan starts to turn pale, remain dark.
Also, pigmented spots often appear among women pregnant. As a rule, they have an irregular shape and sharp outlines. They keep the entire pregnancy, and then disappear on their own. In rare cases, they can remain for life. Most often the spots appear on the temples, on the forehead, the chin, in the nipples, on the genitals.
