Claim 11:
12. A topical sunscreen composition to prevent facultative pigmentation and protect skin from sun damage while permitting the skin to produce vitamin D, the composition comprising:
a combination of UVR filtering agents including octocrylene, butyl methoxy dibenzoylmethane, homosalate, and octyl salicylate, wherein concentrations of the UVR filtering agents is adapted to prevent UVR-induced skin damage while permitting passage of at least 10% of UVB in a range of approximately 290 nm-298 nm to permit vitamin D production; and
a combination of melanogenesis inhibition compounds including 1-methylhydantoin-2-imide at a concentration of about 0.05% to about 5% (w/w), niacinamide at a concentration of about 0.5% to about 10% (w/w), and phenylethyl resorcinol at a concentration of about 0.05% to about 7% (w/w), wherein the combination and concentrations of the melanogenesis inhibition compounds is adapted to inhibit melanogenesis and the corresponding facultative pigmentation of the skin that typically occurs when the skin absorbs the UVB in the range of approximately 290 nm-298 nm, wherein the facultative pigmentation of the skin reduces vitamin D production when the skin absorbs the UVB in the range of approximately 290 nm-298 nm so inhibiting the facultative pigmentation of the skin increases vitamin D production when the skin absorbs the at least 10% of UVB in the range of approximately 290 nm-298 nm.
