Sunscreen That Brightens Skin and Allows Vitamin D Production

US Patent No. 11,964,039 B2;  Ernest T. Armstrong of El Paso, TX was awarded a US patent for a  topical sunscreen composition that prevents facultative pigmentation and protects skin from sun damage while permitting the skin to produce vitamin D.

The composition is comprised of a combination of UVR filtering agents, wherein the combination and concentrations are 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. The UVR filtering agents include octocrylene, butyl methoxy dibenzoylmethane, homosalate and octyl salicylate. The composition also contains  a combination of melanogenesis inhibition compounds 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. 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 increasing the vitamin D production when the skin absorbs the at least 10% of UVB in the range of approximately 290 nm-298 nm.

The composition does not include any ingredients at concentrations that would effectively filter UVB in the range of approximately 290 nm-298 nm.

The combination of melanogenesis inhibition compounds include 1-methylhydantoin-2-imide, niacinamide, and phenylethyl resorcinol.
