Claim 0:
1. 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, wherein the combination and concentrations of the UVR filtering agents is adapted to selectively filter enough light in UVA and UVB rangers 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, wherein the combination of UVR filtering agents include
octocrylene at a concentration of about 0.5% to about 10% (w/w), and
butyl methoxy dibenzoylmethane at a concentration of about 0.5% to about 7% (w/w),
homosalate at a concentration of about 0.5% to about 15% (w/w), and
octyl salicylate at a concentration of about 0.5% to about 10% (w/w); and

a combination of melanogenesis inhibition compounds, wherein the combination and concentrations of the melanogenesis inhibition compounds is adapted to inhibit melanogenesis and the corresponding facultative pigmentation of the skin even though the skin absorbs the at least 10% of UVB in the range of approximately 290 nm-298 nm, wherein the absorption of the UVB in the range of approximately 290 nm-298 nm by the skin typically results in production of melanin by the skin and the corresponding facultative pigmentation of the skin in addition to vitamin D production, wherein the facultative pigmentation of the skin reduces the 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 the vitamin D production when the skin absorbs the at least 10% of UVB in the range of approximately 290 nm-298 nm, wherein the composition does not include any ingredients at concentrations that would effectively filter UVB in the range of approximately 290 nm-298 nm, and wherein the combination of melanogenesis inhibition compounds include 1-methylhydantoin-2-imide, niacinamide, and phenylethyl resorcinol.
