The present disclosure relates to compositions and methods for providing full spectrum photo protection to skin, which includes protection from infrared (IR) radiation and/or visible light in addition to protection from UV radiation. The compositions typically include: (a) silymarin; (b) one or more antioxidants selected from the group consisting of ferulic acid, Vitamin C, polydatin, and hesperetin; (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.

1. A cosmetic composition comprising; (a) 0.001 to 12 wt. %, based on the total weight of the composition, of silymarin;(b) 0.001 to 20 wt. %, based on the total weight of the composition, of one or more antioxidants selected from the group consisting of ferulic acid, Vitamin C, polydatin, and hespe
1. A cosmetic composition comprising; (a) 0.001 to 12 wt. %, based on the total weight of the composition, of silymarin;(b) 0.001 to 20 wt. %, based on the total weight of the composition, of one or more antioxidants selected from the group consisting of ferulic acid, Vitamin C, polydatin, and hesperetin;(c) 0.001 to 30 wt. %, based on the total weight of the composition, of one or more cosmetically acceptable hydrotropes selected from the group consisting of nicotinamide, caffeine, sodium PCA, sodium salicylate, urea, and hydroxyethyl urea; and(d) a cosmetically acceptable carrier; wherein the combination of (a), (b), (c), and (d) alone provides full spectrum protection from ultraviolet (UV) radiation, visible light, and infrared radiation (IR). 2. The composition of claim 1, further comprising: (e) one or more emulsifiers. 3. The composition of claim 2 wherein the total amount of the one or more emulsifiers of (e) in the composition is 0.001 to 10 wt. %, based on the total weight of the composition. 4. The composition of claim 2, wherein the one or more emulsifiers of (e) comprises a nonionic emulsifier. 5. The composition of claim 4, 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 combinatioon thereof. 6. The composition of claim 1, further comprising: (f) one or more UV filters. 7. The composition of claim 6, wherein the nonionic emulsifer comprises a combination of a polyol ester and an ethylene glycol polymer. 8. The composition of claim 6, 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, and a chalcone. 9. The composition of claim 1, wherein the cosmetically acceptable carrier of (c) comprises water, an organic solvent, or a mixture thereof. 10. The composition of claim 1, further comprising: (g) one or more skin active ingredients. 11. The composition of claim 10, wherein the one or more skin active ingredients of (g) are selected from the group consisting of adenosine, ascorbic acid, 2-[4-(2-hydroxyethyl)piperazin-1-yl]ethanesulfonic acid (HEPES), hyaluronic acid, lanolin, citric acid, malic acid, lactic acid, tartaric acid, salicylic acid, vitamin C, a vitamin, a retinoid, retinal, retinoic acid, a carotenoid, an amino acid, a protein, an enzyme, a coenzyme, and a mixture thereof. 12. The composition of claim 1, further comprising: (h) one or more silicon oils. 13. The composition of claim 12, 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 or (2-phenylethyl)trimethylsiloxysilicates, and a mixture thereof. 14. The composition of claim 13, wherein the one or more silicone oils of (h) comprises dimethicone. 15. A method for providing full spectrum photo protection to the skin comprising topically applying to the skin of a subject a composition according to claim 1, wherein full spectrum photo protection provides protection from ultraviolet (UV) radiation, visible light, and infrared radiation (IR). 16. A cosmetic composition comprising; (a) 0.001 to 12 wt. %, based on the total weight of the composition, of silymarin;(b) 0.001 to 20 wt. %, based on the total weight of the composition, of one or more antioxidants selected from the group consisting of ferulic acid, Vitamin C, and polydatin;(c) 0.001 to 30 wt. %, based on the total weight of the composition, of one or more cosmetically acceptable hydrotropes selected from the group consisting of nicotinamide and caffeine;(d) a cosmetically acceptable carrier;(e) 0.001 to 10 wt. %, based on the total weight of the composition, of one or more nonionic emulsifiers; and(f) one or more UV filters; wherein the combination of (a), (b), (c), and (d) alone provides full spectrum protection from ultraviolet (UV) radiation, visible light, and infrared radiation (IR). 17.
