Sunscreen use, even with optimal application, does not hinder vitamin D synthesis in healthy individuals. However, rigorous photoprotection for photosensitive individuals may impact vitamin D levels, necessitating screening and supplementation.
Area of Science:
- Endocrinology
- Dermatology
- Photobiology
- Epidemiology
- Biological Anthropology
Background:
- Global concern exists regarding vitamin D deficiency.
- Debates focus on photoprotection versus solar exposure for vitamin D requirements.
Purpose of the Study:
- To review evidence on sunscreen's influence on vitamin D status.
- To reach a consensus considering other relevant factors.
Main Methods:
- An international expert panel reviewed existing literature.
- Evidence was discussed in a 2017 meeting.
- Assessment of vitamin D status, public health, and photoprotection effects.
Main Results:
- A serum 25(OH)D level of ≥ 50 nmol/L is the target for all.
- Broad-spectrum sunscreens unlikely to compromise vitamin D in healthy populations.
- Vitamin D screening advised for individuals at risk, like those with photosensitivity disorders.
Conclusions:
- Daily sunscreen use does not compromise vitamin D synthesis.
- Photoprotection strategies for photosensitive patients may impact vitamin D status.
- Screening and supplementation are recommended for photosensitive individuals.

Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...
