Abstract
Abstract The present invention provides methods for treating or preventing various dermatological conditions in humans, such as dry, cracked or damaged skin resulting from exposure to sunlight (ultraviolet radiation) and wind, aging effects, general skin dryness, e.g., deficient moisture content, and mild acne. These methods comprise applying an effective amount of a composition to the affected target area, the composition comprising a retinyl palmitate-polypeptide complex of apparent molecular weight of from about 5,000 to about 7,000 daltons, and an isoprenoid compound, e.g., a carotenoid such as beta-carotene.

A method of treating photo damaged skin in a human comprising applying to the affected area of said skin an effective amount of ca composition comprising an extract from yellow or deep green vegetables wherein said extract is characterized by the presence of retinoid binding polypeptides having molecular weight of about 5000 to about 7000 daltons, at least one retinyl fatty acid ester bound to said polypeptides forming a retinyl ester polypeptide complex, and an isoprenoid.
Claim 2
Independent Claim
76 words
A method of treating photo damaged skin in a human comprising applying to the affected area of said skin an effective amount of ca composition comprising an extract from yellow or deep green vegetables wherein said extract is characterized by the presence of retinoid binding polypeptides having molecular weight of about 5000 to about 7000 daltons, at least one retinyl fatty acid ester bound to said polypeptides forming a retinyl ester polypeptide complex, and an isoprenoid.
Claim 3
Independent Claim
87 words
A method of protecting or treating the skin of a human against the abrasive effects of wind comprising applying to the area of said skin to be protected or treated an effective amount of a composition comprising an extract from yellow or deep green vegetables wherein said extract is characterized by the presence of retinal binding polypeptides having molecular weight of about 5000 to about 7000 daltons, at least one retinyl fatty acid ester bound to said polypeptides forming a retinyl ester polypeptide complex, and an isoprenoid.
Claim 4
Independent Claim
87 words
A method of protecting or treating the skin of a human against the abrasive effects of wind comprising applying to the area of said skin to be protected or treated an effective amount of a composition comprising an extract from yellow or deep green vegetables wherein said extract is characterized by the presence of retinal binding polypeptides having molecular weight of about 5000 to about 7000 daltons, at least one retinyl fatty acid ester bound to said polypeptides forming a retinyl ester polypeptide complex, and an isoprenoid.
Claim 5
Independent Claim
76 words
A method of moisturizing skin in a human comprising applying to the area of said skin to be moisturized an effective amount of a composition comprising an extract from yellow or deep green vegetables wherein said extract is characterized by the presence of retinal binding polypeptides having molecular weight of about 5000 to about 7000 daltons, at least on retinyl fatty acid ester bound to said polypeptides forming a retinoid ester polypeptide complex, and an isoprenoid.
Claim 6
Independent Claim
76 words
