摘要:
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. The compositions of the invention also may be used in household items such as candles, deodorizers and pet litter to scavenge reactive oxygen and nitrogen species in the home.

The present invention relates to compositions comprising extracts of Durio zibethinus. The compositions of the present invention are useful for improving the appearance, texture, and/or moisture of mammalian skin. In particular, the compositions of the present invention decrease inflammation in the skin, inhibit matrix metalloprotease-9, which degrades skin proteins such as collagen and elastin, and inhibit melanogenesis in the skin.

A skin whitening composition includes an extract of asparagus obtained by sequentially exposing the asparagus to two or more solvents of varying solvent strengths. The root and shoot portions of the asparagus can be separately used to obtain the extract. The composition can be topically applied to the human skin and can further include one or more cosmetically acceptable ingredients. A method of suppressing melanogenesis includes topically applying to the skin a composition comprising an extract of asparagus obtained by sequentially exposing the asparagus to two or more solvents of varying solvent strengths.

The present invention relates to methods of increasing tyrosinase synthesis, expression, or activity in a cell comprising administering at least one grape seed extract to the cell. The grape seed extract may be obtained by any extraction process including solvent sequential fractionation and supercritical fluid extraction.
摘要:
A dietary supplement including a unique combination of fruits, vegetables, herbs, and optionally vitamins, minerals and specialty ingredients. The supplement can include a fruit ingredient, a vegetable ingredient and an herbal ingredient, wherein the fruit ingredient is at least one of pomegranate and citrus bioflavonoids, wherein the vegetable ingredient is at least one of asparagus, lutein, lycopene and watercress, and wherein the herbal ingredient is at least one of basil, oregano and rosemary. The supplement can be administered to subjects to reduce risk factors in a subject, for example, by lowering homocysteine levels and/or reducing DNA damage. The supplement can increase plasma levels of at least one of vitamin B6, Vitamin B12, folate, and beta-carotene and other vitamins or substances in the subject.
