Does Sunscreen Contain Vitamin D?

Sunscreens can help prevent sunburn, and but allows excellent vitamin D synthesis. Using sunscreen that has high UVA‐PF enables higher vitamin D synthesis, reveals a new study.

Sunscreen may reduce the sun's adverse effects. A sunscreen that is high in UVA radiation enables significantly higher vitamin D synthesis than a low UVA protection factor sunscreen, reveals a new study.//

In a new British Journal of //Dermatology study, however, investigators recorded an increase of vitamin D in participants during a week of cloudless weather, with very high UV index, even when sunscreens were used properly and prevented sunburn.

‘Sunscreens can help prevent sunburn, but allow vitamin D synthesis. A higher UVA‐PF sunscreen enables higher vitamin D synthesis than a sunscreen that is low in UVA‐PF.’

Sunlight contains UVA and UVB radiation, and the latter is essential for vitamin D synthesis. Two sunscreens with the same SPF were compared.

Sunscreen with a high UVA protection factor enabled significantly higher vitamin D synthesis than a low UVA protection factor sunscreen, likely because it allows more UVB transmission.

The findings indicate that the benefits of sunscreen use can be obtained without compromising vitamin D levels.

DNA Sunscreen Protects Skin, Keeps Skin Hydrated
Thin DNA films irradiated with UV rays were designed to be applied as a sunscreen that would protect the skin from DNA damage.

"Sunlight is the main source of vitamin D. Sunscreens can prevent sunburn and skin cancer, but there has been a lot of uncertainty about the effects of sunscreens on vitamin D," said lead author Prof. Antony Young, of King's College London.

"Our study, during a week of perfect weather in Tenerife, showed that sunscreens, even when used optimally to prevent sunburn, allowed excellent vitamin D synthesis."

Can Excessive Use of Sunscreen Cause Vitamin D Deficiency?
Widespread vitamin D deficiency could be due to overuse of sunscreen, restricting exposure to the sun and preventing synthesis of vitamin D.
