The present disclosure relates to a method for preparing an aglycone or hydrolyzed glycoside converted from a glycoside and, specifically, to a method for preparing an aglycone or hydrolyzed glycoside from a glycoside by converting a glycoside into an aglycone form or hydrolyzed glycoside by using a microorganism producing -glycosidase, and then recovering the aglycone or hydrolyzed glycoside accumulated in the cells of the microorganism.

Disclosed is a method of applying a topical skin composition to skin. The method can include applying the composition to skin. The composition can include Silybum marianum fruit extract and Momordica grosvenorii fruit extract.

The present invention relates to a topical composition and more particularly a topical composition for antimicrobial benefit. According to the present invention there is provided a topical composition comprising Niacinamide and picolinamide wherein the molar ratio of Niacinamide to picolinamide is from 1:20 to 20:1.

A therapeutic serum suitable for inclusion in a cosmetic preparation may be produced by stressing a co-culture including proliferative cells. The co-culture of cells may be obtained by growing first culture to less than one-hundred percent confluence on a surface. After a monolayer of first culture is established, a second culture may be seeded onto at least one cell free area on the surface, the resulting co-culture grown to less than one-hundred percent confluence. Additional cultures may then be seeded onto cell free areas of the surface and established until a monolayer having the desired population of cells is obtained. The monolayer is then stressed to obtain a serum by conditioning a collection medium. The obtained serum may be combined with a suitable cosmetic base to provide a cosmetic preparation.

Disclosed is a method of exfoliating skin. The method can include topically applying an effective amount of a composition to skin in need thereof. The composition can include an alpha hydroxy acid, 4-tert-butylcyclohexanol, an aqueous extract of plankton comprising an exopolysacchride synthesized by Vibo alginolyticus, an aqueous extract of Phragmites communis, an aqueous extract of Poria cocos, and an aqueous extract of Cucurbita pepo (pumpkin) seed.

Compositions, kits, and methods for repairing bonds, for example, disulfide bonds, in hair or on the skin are disclosed. The compositions provide improved conditioning benefit for dry hair or moisturize the skin. The compositions also provide a long lasting moisturized feel and smooth feel to the skin or hair, without feeling greasy. The compositions contain one or more compounds that covalently bind at least two thiol groups in the hair or on the skin. Use of the binding compositions prevents reversion of the repaired bonds to their free thiol state, for at least one week or one month, or more, after a single application of the composition. Improved methods of styling hair, for example permanent hair waving, hair curling, hair coloring or highlighting, and hair straightening, are also provided.

The present invention relates to the cosmetic use of an essential oil of Achillea, as an active agent for preventing and/or treating the signs of skin ageing, characterized in that this essential oil of Achillea comprises the following compounds, each present at more than 5% by weight relative to the total weight of the essential oil: artemisia ketone, chrysanthenone (two combined isomers), and ascaridole. It also relates to the associated cosmetic process.

Compositions, methods, and kits for cleansing, moisturizing, soothing, cooling, such as those, for example, that may be used to cleanse, moisturize, soothe, and cool the body or portions thereof.

The present invention features novel cosmetic skin care compositions for improving the appearance of flushed or rosacea-affected skin.

Disclosed is a topical skin composition and methods for its use. The composition can include Silybum marianum fruit extract, Momordica grosvenorii fruit extract, and a cosmetic vehicle comprising water, a moisturizing agent, and a preservative.
