Vitamin D

Exposure to the sun is responsible for over 90% of vitamin D production but can be dangerous, particularly in cases of vitiligo. Thus, individuals affected by this skin condition often fear a deficiency in vitamin D. Is this risk real? Let's explore this question together.

Psoriasis attacks the skin in the form of periodic inflammatory flare-ups. As a chronic disease, it generates both physical and psychological impacts. There is no treatment that permanently cures psoriasis. However, certain treatments can alleviate the symptoms. Moreover, vitamins are allies in mitigating the effects of this skin disease. Which vitamins are suitable for psoriasis? Discover them in this article.

Vitamin D derivatives (calcitriol, calcipotriol) are often prescribed treatments for psoriasis to limit the proliferation of keratinocytes, the main consequence of this skin disease. In the long term, they are generally used as maintenance therapy. At the beginning of the treatment, these slow-acting substances are often combined with a dermocorticoid to enhance their effect.

Vitamin D is an essential element for the body's functioning. It increases the concentration of calcium and phosphorus in the blood, which helps prevent various diseases such as osteoporosis. This fat-soluble vitamin, which is hard to find in food, is synthesized by the body thanks to sunlight. Is there a risk of deficiency in case of insufficient sun exposure?

Exposure to UVB radiation is responsible for over 90% of vitamin D production, but it is also the primary cause of sunburn and skin cancer. Therefore, the daily application of sunscreen is recommended to reduce the harmful effects of the sun. However, some fear that their widespread use, especially those with high sun protection factors, may block UVB rays and prevent vitamin D synthesis, thereby causing a deficiency. Can sunscreen indeed compromise this reaction?
