A method for treating skin of a person is disclosed. The method can include topically applying to the skin of the person a composition comprising an effective amount of an aqueous, alcoholic, or aqueous-alcoholic extract from Livistona chinensis, wherein the composition reduces tyrosinase activity or melanin production in the skin, increases antioxidant activity in the skin, and/or increases skin moisture content.

Hair treatment and hair lightening compositions, methods of making and use, and to kits comprising the compositions. The components of the hair treatment compositions may be included in hair lightening compositions and used to lighten and/or color hair. The hair treatment compositions include: (a) one or more polycarboxylic acids, and/or a salt thereof; (b) one or more amino acids, and/or a salt thereof; and (c) one or more antioxidant comprising an aromatic ring having two alcohol functional groups. The hair lightening compositions further include (d) one or more bleaching agents.

A rheological solid personal care composition comprises a crystallizing agent, a suspension agent, an insoluble active, and an aqueous phase. A process for the manufacture of a rheological solid composition comprises the steps of: provision and heat up of an aqueous solution of sodium chloride, and sodium hydroxide; addition of an emulsifier, preferably palmitic acid, in order to obtain an emulsifier main mix, preferably a sodium palmitate soap main mix; addition of a suspension agent, preferably xanthan gum and glycerin, to the emulsifier main mix; addition of an insoluble active premix to the emulsifier main mix to obtain a blend, the insoluble active premix preferably being a petrolatum-based premix of topical drug actives, the topical drug active preferably selected from the group of: menthol, nutmeg, camphor, eucalyptus, cedar leaf, thymol, and any combinations thereof; cool down of the blend in order to form a crystalline structure of the rheological solid composition; optionally, addition of a hygroscopic stabilizer to the blend in order to stabilize the crystalline structure, the hygroscopic stabilizer preferably being sodium lactate.

New extracts of Nannochloropsis sp. and related species of Nannochloropsis are suggested, obtainable by treating said microalgae with a solvent selected from the group consisting of C.sub.1-C.sub.1 aliphatic alcohols, ethyl acetate, water or their mixtures, removing the dissolved extracts from the residues and recovering the pure extracts from the solvent. The extracts show excellent properties particularly in modulating the metabolism of human skin and hair follicles.
