Vitamin D and your skin 

Vitamin D is an important micronutrient that can be obtained from several food items, such as fish, meat, egg yolks, and mushrooms. One can also take supplements, and of course, the sun also stimulates vitamin D production in the body. Low vitamin D levels can cause several health issues, such as increased muscle and bone pain, fatigue, weak immunity, and many more.

Vitamin D deficiency also affects skin and hair health. Low levels can cause acne, skin rashes, and a rise in eczema and psoriasis. It can also cause hair fall, as vitamin D is linked to keratinocytes, a type of cell essential for hair growth. 

Does sunscreen cause vitamin D deficiency?

As per several dermatologists and researchers, sunscreen does not affect the vitamin D levels of your body. No person applies the high amount of sunscreen required to block all the UV rays from the sun. 

Experts revealed that a large number of people do not reapply sunscreen after sweating or any physical activity, which enables the body to absorb UV rays.
