Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Vitamin D has a scientifically supported role in skin health, though its primary uses are related to specific skin disorders rather than general skin support. Vitamin D receptors are present in many cells of the skin, including keratinocytes, and vitamin D helps regulate cellular proliferation, differentiation, and immune function in the skin. The most well-established clinical use of vitamin D is in the topical treatment of psoriasis; synthetic vitamin D analogues (such as calcipotriol) are effective for reducing psoriatic plaques. There is also evidence that vitamin D deficiency can be associated with various skin conditions, including atopic dermatitis and increased susceptibility to skin infections, though causation is not always clear. Some observational studies suggest that adequate vitamin D status may support wound healing and skin barrier function, but robust clinical trial data for supplementation in the general population for skin health are limited. Oral vitamin D supplementation is not universally recommended for skin health except in cases of deficiency or specific dermatological indications. Thus, while there is scientific validation for vitamin D’s role in certain skin conditions, its use as a general skin health supplement is less clearly supported.
