A carotenoid substance called zeaxanthin, when ingested orally at suitable dosages, can provide effective protection against sunburns and darken the skin to emulate a healthy suntan. Zeaxanthin may induce: (i) a mild but noticeable tinting, shading, or darkening of skin color, comparable to a mild suntan; (ii) a substantial increase in the person's ability to withstand elevated levels of sun or UV exposure; and, (iii) an increased ability of reddened and sunburned skin to convert into intact skin that looks browned and healthily tanned. Topical formulations containing zeaxanthin can be administered to the skin during the time period of ingesting the oral formulation to further protect the skin and provide an additional darkening of the skin.

1. A method of providing increased sunburn protection to the skin, comprising: ingesting, over a period of time, at least 10 milligrams per day of zeaxanthin, the ingested zeaxanthin being in an oral formulation that is one of a group consisting of a capsule, a tablet, and a liquid, the zeaxanthin in the oral formulation being predominantly present in the form of the R-R stereoisomer of zeaxanthin; andduring the period of time, applying a topical formulation to the skin so as to darken the skin, the topical formulation being in the form that is one of a group consisting of a lotion, an ointment, or a cream, the topical formulation including zeaxanthin. 2. The method of claim 1, wherein the oral formulation provides at least about 20 milligrams per day of zeaxanthin. 3. The method of claim 1, wherein the topical formulation includes a permeation-enhancing agent to increase permeation of the zeaxanthin from the topical formulation into epidermal tissue layers of the skin. 4. The method of claim 3, wherein the permeation-enhancing agent is dimethyl sulfoxide. 5. The method of claim 1, wherein the zeaxanthin is present in the oral formulation in an oily carrier substance. 6. The method of claim 1, wherein the oral formulation includes at least one second active agent, the second agent is selected from the group consisting of melanocyte-stimulating hormone and analogs, non-zeaxanthin carotenoids, tyrosine, green tea extract, lutein, lipoic acid, and selenomethionine. 7. The method of claim 6, wherein the zeaxanthin is the predominate carotenoid in the oral formulation. 8. The method of claim 6, wherein the topical formulation further includes at least one of dihydroxyacetone, erythrulose, and tyrosine. 9. The method of claim 1, wherein the ingesting, by itself, causes a darkening of the skin. 10. The method of claim 9, wherein the darkening of the skin from the ingesting darkens the skin by at least two color shades when measured using a dermatologist skin chart. 11. The method of claim 1, wherein the zeaxanthin is the predominate carotenoid in the oral formulation. 12. The method of claim 11, wherein the oral formulation further includes lutein. 13. A method of providing increased sunburn protection to the skin, comprising: ingesting, over a period of time, at least 10 milligrams per day of zeaxanthin, the ingested zeaxanthin being in an oral formulation that is one of a group consisting of a capsule, a tablet, and a liquid, the zeaxanthin in the oral formulation being predominantly present in the form of the R-R stereoisomer of zeaxanthin, the zeaxanthin is the predominate carotenoid in the oral formulation; andduring the period of time, applying a topical formulation to the skin so as to darken the skin, the topical formulation being in the form that is one of a group consisting of a lotion, an ointment, or a cream, the topical formulation including zeaxanthin and a permeation-enhancing agent to increase permeation of the zeaxanthin from the topical formulation into tissue layers of the skin. 14. The method of claim 13, wherein the oral formulation provides at least about 20 milligrams per day of zeaxanthin. 15. The method of claim 14, wherein the oral formulation further includes lutein. 16. The method of claim 13, wherein the permeation-enhancing agent is dimethyl sulfoxide. 17. The method of claim 13, wherein the topical formulation further includes at least one of dihydroxyacetone, erythrulose, and tyrosine.
