Abstract: Methods of reducing cellular damage are described that include (a) administering to the mammal an oral dosage form comprising a therapeutically effective amount of a first antioxidant, and (b) administering to the mammal a topical dosage form comprising a therapeutically effective amount of a second antioxidant, wherein at least one of the first antioxidant and the second antioxidant comprises acerola concentrate. Methods of inhibiting free radical production, methods of scavenging free radicals, and kits for reducing cellular damage are also described.

Abstract: Topical skin compositions include a complex containing components to provide a defense against the various pathway mechanisms of free radicals, reactive oxygen species, reactive nitrogen species, and other oxidizing species on the human body including the skin. The compositions may be administered by topically applying them in an amount to inhibit those mechanisms. The compositions and methods are directed to the prevention of the adverse or detrimental effects of free radicals, reactive oxygen species, reactive nitrogen species, and other oxidizing species on the human body including the skin. Thus, the compositions according to the invention improve barrier function, inhibit elastase and collagenase, and/or promote synthesis of collagen and elastin.

Abstract: Methods and compositions for scavenging reactive molecules, including free radicals, reactive oxygen and reactive nitrogen species, in the air are described. More specifically, methods and compositions for scavenging reactive molecules in the air before the reactive chemicals contact the skin or other tissue surface are described. The scavenging occurs by topical application of a scavenging agent, such as a volatile antioxidant, to the skin, or by releasing a scavenging agent, such as a volatile antioxidant, into the air near or surrounding the skin. Additionally, the present invention relates to compositions comprising a scavenging agent in combination with a carrier or vehicle, wherein the scavenging agent may include fragrances or fragrance components having antioxidant properties and wherein the scavenging agent scavenges reactive molecules in the air space surrounding a site on the skin where the composition has been applied.
