How is Vitamin D linked to skin health?

It is a little known fact that vitamin D is very important for healthy skin

Deficiencies have been linked to skin conditions such as acne and eczema and unfortunately in the U.K, due to long winter seasons and time spent indoors, many people are thought to be deficient in vitamin D.  Supplementation, both orally and topically on the skin, could be beneficial to some. Research has shown that both children and adults with eczema are more likely to have low levels of vitamin D and lower vitamin D levels are also linked to more severe skin symptoms.

Why is Vitamin D important for the skin?

Skin renewal processes

Vitamin D is primarily sourced from exposure to sunlight and is made in the epidermis by keratinocytes. Studies have shown how vitamin D production in the skin helps regulate the skin renewal process. Loss of cells on the skin’s surface must be replaced in a vitamin D- dependent renewal process, for healthy skin cell turnover. Keratinocytes provide new cells for the skin’s surface which is important for healthy skin and keeping the skin soft and moisturised.

Photoprotective benefits

Vitamin D has been shown to protect the skin from photodamage from sunlight; this is incredibly important in reducing damage and protecting skin cells from potential cancer causing processes due to UVA-UVB exposure Photoageing is also a key factor in skin’s appearence and a premature ageing and vitamin D may provide some protection against sun damage.

Wound healing

Vitamin D influences the activity of a protein which promotes wound healing and restores healthy skin; This process helps moderate inflammation, protects the skin from bacteria and assists tissue repair.

Skin conditions

While more conclusive research is needed, some studies have found that through Vitamin D supplementation, chronic skin conditions such as psoriasis and eczema can be improved. Vitamin D can also be sourced through the diet, especially present in some fortified foods, and your G.P or dermatologist  may be able to advise on the appropriate supplementation for your needs.
