Overview

• Health agencies confirm that regular broad-spectrum sunscreen use does not lead to vitamin D deficiency, as minimal unprotected exposure suffices for synthesis.
• Experts advise exposing face, hands, and arms without sunscreen for 10–15 minutes twice weekly to maintain adequate vitamin D levels.
• Updated guidelines stress the importance of applying sunscreen in sufficient quantities—approximately 3–4 tablespoons per adult—and reapplying every two hours.
• Combining sunscreen with other protective measures, such as shade, long clothing, and UV-index monitoring, enhances skin safety and reduces cancer risks.
• Public misconceptions about sunscreen blocking vitamin D or the idea of 'healthy tanning' are being addressed through updated evidence and education efforts.
