Melodie Dewever, Certified Alternative Practitioner and expert Sunday Natural France reveals the dermatological side of vitamin D benefits.
What positive effects can vitamin D have on our skin?
The skin has several functions:
● a protective function: it protects against external attacks,
● an informative role : thanks to its nerve endings that communicate with the outside world
● a metabolic role : It is involved in thermoregulation, the metabolism of mineral salts and the synthesis of vitamin D
The beneficial effects of vitamin D
– It is necessary for the development, maintenance and good mineralization of the skeleton, promoting the absorption of calcium and phosphorus in the intestine and their fixation to the skeleton. It is therefore very important during growth, during menopause and for the elderly. It thus contributes to the promotion of skin renewal
– It promotes reproduction and contributes to the proper functioning of the immune system. The skin is a protective barrier to the outside world and vitamin D helps maintain and strengthen its functions Fence (Bacteria that cause acne, inflammation, wounds, atopic dermatitis…)
– According to an Inserm study, it would reduce symptoms in cases of psoriasis
Why are summer and sunshine periods and factors that vitamin D?
Vitamin D has two origins:
– Vitamin D2 (ergocalciferol), produced by plants
– Vitamin D3 (cholecalciferol) of animal origin
The human organism transforms the Vitamin D2 in Vitamin D3. Vitamin D can be obtained from lanolin, which is obtained from sheep’s wool. It can also be found in plant form, from yeast exposed to ultraviolet rays.
We can synthesize vitamin D at the level of the epidermis under the action of UVB. This synthesis is mainly carried out from April to September (in France), the months when the sun is at its greatest. Theoretically, 15 to 20 minutes of sunshine in summer is enough to cover 70% of the demand.
attention However, vitamin D is stored in adipose tissue, liver and muscle. As with other vitamins, it is not easily excreted. The exposure should therefore not be excessive, which is why it is always necessary to protect yourself (hat, sunscreen).
Are all skin types the same when it comes to vitamin D? ? Why ?
Not all skins are not equal against vitamin D. For example, fair skin tends to avoid exposure to sunburn. So we can see a deficiency in these people. People with dull or dark skin have a higher need for sunlight to produce the same dose of vitamin D.
We usually give a Addition Children under 2 years old and the elderly. In fact, their exposure is generally lower, but vitamin D is essential for bone system development/support.
In any case, it is essential consult a professional to determine the need for supplements.
How should we consume it so that our skin can reap the benefits of vitamin D?
That Vitamin D deficiency is very common. According to studies, almost 80% of the French would be affected by peak rates or a more significant shortage, with significant differences depending on the more or less sunlit regions. Air pollution would be one of the main reasons for the insufficient vitamin D levels in France.
The diet is also low in foods rich in vitamin D. It’s often easier to have a supply of vitamin D dietary supplements. It is also possible to expose your forearms to the sun for 15 to 20 minutes a day. In any case, it is important to consult a professional to determine the possible need for supplementation.
