There are thousands of skin problems, and spots account for half of them, and many girls have pigmentation.
Pigmentation is similar to blackening, which is a change in the metabolism of melanin in the case of ultraviolet light or hormone levels and changes in the state of the skin. This leads to "increased melanin production", which slowly accumulates and causes pigmentation.
UV rays cause the accumulation of melanin, which is the basis for pigmentation. Therefore, almost all pigmentation is related to UV rays. Now let's analyze the main causes of the major pigmentation.

Freckles are only the size of a grain of rice or the size of a pinpoint and are mainly distributed on the cheeks, nose, neck, arms, and other places that are easily exposed to the sun. Freckles can be classified as congenital or acquired.
In addition to congenital freckles, they also like to grow on the skin of people who do not have sun protection habits. When the normal number of melanocytes in the body secrete an excessive amount of melanin, freckles will easily appear under exposure to ultraviolet rays, the number will increase and the color of the spots will get darker.
Therefore, no matter whether indoors or outdoors, you need to use sunscreen products all year round, together with whitening products to improve and help reduce pigment accumulation.

Sunburn spots are usually irregularly distributed and mainly grow on the cheeks! It is mainly caused by the increase of melanin pigment in the underlying skin layer.
