The formation of spots occurs due to an alteration in skin color due to a problem in the production of melanin, a substance produced by melanocytes or, rather, the cells found in the epidermis. And when we expose ourselves to the sun, they begin to produce melanin, which gives that divine tanned tone that we like so much.
However, the fact that the dermis tans when in contact with the sun’s rays is a defense mechanism to prevent it from burning and damaging the cell nuclei. That’s why When we have golden skin, it means there has been sun damage. and our body has protected itself from it, so actually he healthy tan does not exist.
Why is melanin production altered?
There are different causes:
- Our skin has memory and prolonged exposure to the sun causes melanocytes to be damaged, causing an increase or decrease in the production of the sun. melanin. This is the reason why, In autumn, we notice the appearance of new spotsand these, although they fade, will appear again. That is, we can remove the color, but not eliminate them, so when we expose them once again they will appear. On the contrary, white spots may also appears when our melanocytes are not able to produce melanin.
- Sun damage is cumulative and, as we get older, it is common to see spots appear if you have not protected yourself well during the previous years.
- Another reason is the increase or decrease in the number of melanocytes. Or as a consequence of the abnormal location of melanin or melanocytes.

- More superficial stains: They arise because the tan disappears unevenly in different parts of the body. Solution: They are easily removed with the use of an exfoliant applied to damp skin. It should be massaged using light pressure to eliminate dead cells from the stratum corneum responsible for the difference in skin tone.
