The increased use of sunscreens, while limiting damage to the DNA, may promote cancer growth by preventing vitamin D synthesis in the skin. According to the present invention, the beneficial effects of UV radiation are obtained by incorporating vitamin D into the topical sunscreen or after sun lotions. Application of the sunscreen prevents the harmful effects of UV radiation and the included vitamin D is activated by the skin to calcitriol for cancer prevention. Because calcitriol also promotes cellular growth and differentiation, the topical sunscreen or after sun product with vitamin D may be of benefit for photoaging.
