A composition suitable for providing protection against ultraviolet radiation containing one or more active ultraviolet radiation absorber through which ultraviolet B radiation is permitted to enter the skin in an amount sufficient for the body to produce a healthful and disease-opposing quantity of vitamin D 3 and chemical precursors thereof. The composition is particularly used in sunscreens promoting on the one hand vitamin D 3 production, on the other hand protecting the skin against harmful ultraviolet radiation. |
