If black skin is the best protected from the sun thanks to its high level of melanin, this natural tolerance is not without limit. Brown spots, sunburn, black and mestizo skin are not immune to the harmful effects of the sun , especially when they live in a temperate climate where the skin is no longer used to being exposed. In a temperate climate, dark skin tends to lighten. If they are subjected to sun exposure to which they are no longer accustomed, they need an adaptation period of about a week before regaining all their natural protection. A period during which it is better to be careful and use sunscreens with a minimum protection factor SPF 30 for the body and SPF 50 for the face. It is the level of melanin that determines the color of the skin and its greater or lesser ability to filter UV rays. But natural protection is never complete and even for the darkest skin, the sun remains an enemy that you have to learn to be wary of.
Despite the influence of the sun on skin aging, black skin wrinkles little, thanks to its good elasticity. On the other hand, pigment spots that appear or reactivate under the effect of the sun are a concern for many women with black skin.
Sun exposure can promote the appearance of dark spots , especially on the face, décolleté and neck.
Brown spots are revealed by the first sun exposures and are aggravated in summer. During the summer season, when sun exposure is high, the skin is subjected to intense oxidative stress due to UV rays. The body sets up a defense system composed of 3 enzymes: SOD (superoxide dismutase) , Glutathione peroxidase and Catalase to form an internal shield for your skin . In a significant situation of oxidative stress , this system can be overwhelmed and imperfections appear. Opt for a diet rich in antioxidants in the summer and you can support your body with natural oral solutions.
