The compositions typically include: (a) baicalin; (b) one or more antioxidants selected from the group consisting of venuceane, polydatin, hesperetin, mango leaf extract, vitamin C; (c) optionally, one or more solubilizers; and (d) a cosmetically acceptable carrier. The compositions are unique in that the combination of (a), (b), optional (c), and (d) alone, provide at least full spectrum protection from ultraviolet radiation (UV), visible light, and infrared radiation (IR). The composition can additionally, optionally, include one or more UV filters to further enhance protection from UV radiation. ## Claims ### Claim 1 A cosmetic composition comprising; (a) baicalin; (b) one or more antioxidants selected from the group consisting of venuceane, polydatin, hesperetin, mango leaf extract, vitamin C; (c) optionally, one or more solubilizers; and (d) a cosmetically acceptable carrier; wherein the combination of (a), (b), optional (c), and (d) alone, provide full spectrum protection from ultraviolet radiation (UV), visible light, and infrared radiation (IR). ### Claim 2 (depends on 1) The composition of claim 1 wherein the total amount of the baicalin of (a) is 0.001 to 12 wt. %, based on the total weight of the composition. ### Claim 3 (depends on 1) The composition of claim 1, wherein the total amount of the one or more antioxidants of (b) is 0.001 to 20 wt. %, based on the total weight of the composition. ### Claim 4 (depends on 1) The composition of claim 1, wherein the composition comprises the one or more solubilizers of (c). ### Claim 5 (depends on 4) The composition of claim 4, wherein the one or more solubilizers of (c) comprises one or more cosmetically acceptable hydrotropes selected from the group consisting of nicotinamide, caffeine, sodium PCA, sodium salicylate, urea, hydroxyethyl urea, and a mixtures thereof. ### Claim 6 (depends on 4) The composition of claim 4, wherein the total amount of the one or more hydrotropes is 0.001 to 30 wt. %, based on the total weight of the composition. ### Claim 7 (depends on 1) The composition of claim 1, further comprising: (e) one or more emulsifiers. ### Claim 8 (depends on 7) The composition of claim 7, wherein the total amount of the one or more emulsifiers of (e) is 0.001 to 10 wt. %, based on the total weight of the composition. ### Claim 9 (depends on 8) The composition of claim 8, wherein the one or more emulsifiers of (e) comprises a nonionic emulsifier. ### Claim 10 (depends on 9) The composition of claim 9, wherein the nonionic emulsifier is selected from the group consisting of a polyol ester, a glycerol ether, an oxyethylenated, an oxypropylenated ether, an ethylene glycol polymer, and a combination thereof. ### Claim 11 (depends on 10) The composition of claim 10, wherein the nonionic emulsifer comprises a combination of a polyol ester and an ethylene glycol polymer. ### Claim 12 (depends on 1) The composition of claim 1, further comprising: (f) one or more UV filters. ### Claim 13 (depends on 12) The composition of claim 12, wherein the one or more UV filters of (f) are selected from the group consisting of a para-aminobenzoic acid derivative, a salicylic derivative, a cinnamic derivative, a benzophenone or an aminobenzophenone, an anthranillic derivative, a β,β-diphenylacrylate derivative, a benzylidenecamphor derivative, a phenylbenzimidazole derivative, a benzotriazole derivative, a triazine derivative, a bisresorcinyl triazine, an imidazoline derivative, a benzalmalonate derivative, a 4,4-diarylbutadiene derivative, a benzoxazole derivative, a merocyanine, malonitrile or a malonate diphenyl butadiene derivative, a chalcone, and a mixture thereof. ### Claim 14 (depends on 1) The composition of claim 1, wherein the cosmetically acceptable carrier of (c) comprises water, an organic solvent, or a mixture thereof. ### Claim 15 (depends on 1) The composition of claim 1, further comprising: (g) one or more skin active ingredients. ### Claim 16 (depends on 1) The composition of claim 1, further comprising: (h) one or more silicon oils. ### Claim 17 (depends on 16) The composition of claim 16, wherein the one or more silicon oils of (h) are selected from the group consisting of polydimethylsiloxanes (PDMSs), polydimethylsiloxanes comprising alkyl or alkoxy groups which are pendent and/or at the end of the silicone chain, which groups each contain from 2 to 24 carbon atoms, or phenyl silicones, such as phenyl trimethicones, phenyl dimethicones, phenyl(trimethylsiloxy)diphenylsiloxanes, diphenyl dimethicones, diphenyl(methyldiphenyl)trisiloxanes, (2-phenylethyl)trimethylsiloxysilicates, and a mixture thereof. ### Claim 18 (depends on 17) The composition of claim 17, wherein the one or more silicone oils of (h) comprises dimethicone. ### Claim 19 (depends on 1) The composition of claim 1, wherein the one or more antioxidants of (b) comprises polydatin. ### Claim 20 (depends on 1) A method for providing full spectrum photo protection to the skin comprising topically applying to the skin of a subject a composition of claim 1, wherein the combination of (a), (b), optional (c), and (d) alone, provide full spectrum protection from ultraviolet radiation (UV), visible light, and infrared radiation (IR).
