The importance of vitamin D in skin diseases

Vitamin D plays a supportive and protective role in the treatment of many skin diseases.

Its effects on the skin include inhibiting keratinocyte proliferation, providing antioxidant effects, and regulating immune responses by acting on lymphocytes.

In psoriasis, there is a disruption in keratinocyte proliferation, which leads to scaling in patients. Vitamin D has been found effective in the treatment of psoriasis. It can be used both topically as a cream and systemically.

In atopic dermatitis, also known as childhood eczema, vitamin D is an effective supportive treatment due to its ability to suppress inflammation and its antimicrobial properties.

In vitiligo, or depigmentation disorder, vitamin D is used because it supports pigment production and suppresses inflammation.

Vitamin D treatment has also been found effective in the treatment of warts, alopecia areata, morphea, and ichthyosis, also known as fish scale disease.

In summary, vitamin D deficiency plays a significant role in skin diseases as it does in many other conditions. Replacement therapy is crucial in cases of deficiency.
