In May 2019 researchers from France, Belgium, USA, Brazil, Germany, Australia, Senegal and the UK published their review of the medical scientific literature to assess the association between vitamin D status and whether there is any effect on levels with the use of sunscreen photoprotection. There is a global concern about vitamin D deficiency which has fueled debates on the use of sunscreens and the importance of solar exposure to meet vitamin D requirements. A vitamin D level of over 50 nmol/L is the target for all individuals. Results showed that broad-spectrum sunscreens, that prevent erythema, are unlikely to compromise vitamin D levels in healthy populations. Patients with photosensitivity disorders, who require rigorous photoprotection, should however receive vitamin D screening. Supplementation is also advised for this group.
