Protection against sunburn and skin problems with topical and orally-ingested dosages of zeaxanthin
Zeaxanthin is ingested orally at suitable dosages that gives skin a darker tint that emulates a healthy suntan and that reduces the severity of unwanted skin discoloration or irregularities. In tests involving adults, it was found that zeaxanthin dosages of 30 to about 80 mg per day were sufficient to induce a mild but noticeable tinting, shading, or darkening of skin color, comparable to a mild suntan, a substantial increase in the person's ability to withstand elevated levels of sun or UV exposure without any subsequent pain or discomfort, and without the subsequent peeling and flaking that characterizes sunburns, and an increased ability of reddened and sunburned skin to convert into intact skin that looks browned and healthily tanned. The topical application of zeaxanthin can further enhance the darkening of the skin and reduce the severity of unwanted skin discoloration or irregularities.
1. A method of reducing the incidence or severity of an unwanted skin discoloration or irregularity, comprising:
ingesting, over a period of time, at least 20 milligrams per day of zeaxanthin, the ingested zeaxanthin being in an oral formulation presented in a form of at least one of the group consisting of a capsule, a tablet, and a liquid, the zeaxanthin being the predominate carotenoid in the oral formulation, the zeaxanthin being predominantly present in the form of the R-R stereoisomer of zeaxanthin, the oral formulation being adapted to reduce the incidence or severity of an unwanted skin discoloration or irregularity; and
during the period of time, applying a topical formulation to a location on the skin having the unwanted skin discoloration or irregularity, the topical formulation increasing an antioxidant concentration within and/or beneath the skin.
2. The method of claim 1 , wherein the oral formulation further includes at least one oil.
3. The method of claim 1 , wherein the oral formulation includes at least one second active ingredient selected from the group consisting of melanocyte-stimulating hormone and analogs, non-zeaxanthin carotenoids, tyrosine, green tea extract, lutein, lipoic acid, and selenomethionine.
4. The method of claim 3 , wherein the second active ingredient includes at least a green tea extract and zinc.
5. The method of claim 1 , wherein the oral formulation further includes a plurality of vegetable oils, zinc, and green tea extract.
6. The method of claim 1 , wherein the oral formulation further includes lutein.
7. The method of claim 1 , wherein the topical formulation includes zeaxanthin.
8. A method of reducing the incidence or severity of an unwanted skin discoloration or irregularity, comprising:
ingesting, over a period of time, at least 20 milligrams per day of zeaxanthin, the ingested zeaxanthin being in an oral formulation presented in a form of at least one of the group consisting of a capsule, a tablet, and a liquid, the zeaxanthin being the predominate carotenoid in the oral formulation, the zeaxanthin being predominantly present in the form of the R-R stereoisomer of zeaxanthin, the oral formulation further including at least one of zinc, green tea extract, and lipoic acid, the oral formulation for reducing the incidence or severity of an unwanted skin discoloration or irregularity; and
during the period of time, applying a topical formulation to a location on the skin having the unwanted skin discoloration or irregularity, the topical formulation increasing an antioxidant concentration within and/or beneath the skin.
9. The method of claim 8 , wherein the topical formulation includes zeaxanthin.
10. The method of claim 8 , wherein the oral formulation further includes a plurality of oils, zinc, lipoic acid, and green tea extract.
11. The method of claim 8 , wherein the oral formulation further includes lutein.
12. A method of reducing the incidence or severity of an unwanted skin discoloration or irregularity, comprising:
ingesting, over a period of time, at least 20 milligrams per day of zeaxanthin, the ingested zeaxanthin being in an oral formulation presented in a form of at least one of the group consisting of a capsule, a tablet, and a liquid, the zeaxanthin being the predominate carotenoid in the oral formulation, the zeaxanthin being predominantly present in the form of the R-R stereoisomer of zeaxanthin, the oral formulation being adapted to reduce the incidence or severity of an unwanted skin discoloration or irregularity; and
during the period of time, applying a topical formulation to a location on the skin having the unwanted skin discoloration or irregularity, 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.
13. The method of claim 12 , wherein the oral formulation further includes lutein.
14. The method of claim 13 , wherein the oral formulation further includes at least one of zinc, green tea extract, and lipoic acid.
15. The method of claim 12 , wherein the oral formulation further includes at least one of zinc, green tea extract, and lipoic acid.
