Our skin has a characteristic and uniform color, thanks to a natural pigment that exists in our body, melanin. This is responsible for protecting the skin against UV rays, also giving rise to the tan tone. However, it is not only sun exposure that stimulates melanin; other factors can trigger an increase in its production, namely hormones, age, and skin lesions or inflammation.
When the production of melanin by melanocytes is no longer normal, pigmentation problems may arise in the skin, which may require medical care and monitoring. Thus, we can have hyperpigmentation, which is a skin change that manifests itself as spots or darkened areas on the skin, or a depigmentation/hypopigmentation, which is responsible for the appearance of lighter areas of the skin. The latter is usually associated with diseases such as vitiligo or albinism.
Melanocytes are then stimulated by UV rays, which pass through the epidermis, to produce melanin. However, some of these melanocytes are constantly stimulated, causing them to produce melanin in large and abnormal amounts, on a continuous basis. When it is not evenly distributed on the skin surface, it ends up accumulating in certain areas, causing dark spots. In addition, hyperpigmentation also increases with cell aging, so age is a factor that aggravates this skin problem.
Although it is better to prevent its appearance, it is possible to help reduce hyperpigmentation. It is a time-consuming process and where the results appear progressively, but in which it is possible to uniform the skin tone. There are three main actions that the active ingredients can take: regulating the formation of tyrosinase (the enzyme responsible for the production of melanin), renewing the superficial layer of the skin, and depigmenting the existing spots. In this specific case, there are several cosmetic options that can be used as a treatment. My advice is on the MartiDerm DSP, Lierac Lumilogie, or Neoretin ranges, which present several solutions that can be used together to optimize the results, correcting the existing dark spots and preventing the appearance of new ones.
Therefore, with sun exposure playing such a relevant role in the appearance and aggravation of hyperpigmentations, it is essential to include sunscreen in the daily routine as prevention. Although it is important to use a photoprotector throughout the year, even to prevent skin aging, the reality is that, with the arrival of spring, it becomes even more urgent to use it. Thus, to prevent the appearance of dark spots it is recommended to use a sunscreen with a minimum of Sun Protection Factor (SPF) 30, protect the skin from the sun with the use of a hat or favoring the shade places, and take specific dietary supplements before and during sun exposure, which prepare the skin to receive solar radiation. As a range of sun protection, I advise Heliocare, which offers sunscreens for all skin types, with color and without color, and dietary supplements that help strengthen the skin barrier.
