Vitamin D deficiency can lead to inflammation, infection, and poor immunity. Sunscreens reduce solar exposure and intake of this vitamin. Global debates are raging to establish the link between photoprotection and vitamin D deficiency. The objective of this study is to understand the photoprotection’s influence on vitamin D.
A literary review helped to arrive at a consensus. A global panel of 13 experts from dermatology, photobiology, biological anthropology, epidemiology, and endocrinology met for a 1-day meeting. They discussed the evidence and examined public health perspectives. They also set the assessment methods and vitamin D status determinant factors and assessed the effects of sun exposure and photoprotection.
A serum level ≥ 50 nmol L−1 25(OH)D was the overall target for all individuals. Healthy people can use broad-spectrum sunscreens, with high UVA, to prevent erythema. Patients with photosensitivity disorders and hypovitaminosis risks should avoid sunscreens. They can consume supplements and undergo Vitamin D screening.
Sunscreen use for daily and recreational photoprotection can continue. Even under optimal conditions, it does not compromise vitamin D synthesis. But protective clothing and shade seeking behavior can compromise the Vitamin D status in photosensitivity disorder patients.
