Disclosed is a method for treating skin. The method can include topically applying to skin in need thereof a composition comprising effective amounts of Arctium lappa root extract and Epilobium angustifolium extract to reduce expression of a pro-inflammatory cytokine of IL-8, IL-2, or TNF- in the skin.

The present disclosure describes a topical composition, and related masks comprising the compositions disclosed herein, for applying to skin for treating acne or skin rejuvenation, the compositions comprising a light activated enzymatic extract; adaptogenic Baobab (Adansonia digitata) seed extract; adaptogenic wild indigo (Tephrosia purpurea) extract; pre- and/or pro-biotic extracts; and a carrier. The mask may be embodied in, or comprise, a hydrogel matrix or a biocellulose material or other fibrous material.

An improved pasteurisation protocol for pasteurising microbial cells is disclosed. The protocol has three stages, a first heating stage, a second plateau stage at which the cells are held at a (maximum and) constant temperature, and a third cooling stage. Both the heating and the cooling stages are rapid, with the temperature of the cells passing through 40 to 80 C. in no more than 30 minutes in the heating stage. The heating rate is at least 0.5 C./minute and during cooling is at least 0.5 C./minute. The plateau maximum temperature is from 70 to 85 C. By plotting the pasteurisation protocol on a time (t, minutes) versus temperature (T, C.) graph, one obtains a trapezium having an area less than 13,000 C. minute. Not only does this result in a smaller energy input (and so a reduction in costs), but a better quality (and less oxidized) oil results having a peroxide value (POV) of less than 1.5 and an anisidine value (AnV) of less than 1.0.

Provided herein are microalgal skin care compositions and methods of improving the health and appearance of skin. Also provided are methods of using polysaccharides for applications such as topical personal care products, cosmetics, and wrinkle reduction compositions. The invention also provides novel decolorized microalgal compositions useful for improving the health and appearance of skin. The invention also includes insoluble polysaccharide particles for application to human skin.

A subject-matter of the invention is a process for dyeing keratinous substances, in particular keratinous fibers, comprising the application, to the said keratinous fibers: of at least one composition A comprising at least one non-ionic alkylpolyglucoside surfactant, at least one metal salt and at least one thickening polymer and of at least one composition B comprising one or more ortho-diphenol derivative(s).

A cosmetic composition including -polyglutamic acid or a salt thereof as active ingredients is made of from 0.01% to 5% by weight of -polyglutamic acid (-PGA) or a salt thereof and from 0.02% to 8% by weight of chlorella growth factor (CGF) based on a total weight of the cosmetic composition. The average molecular weight of the -polyglutamic acid or the salt thereof is between 110.sup.6 Da and 310.sup.6 Da.
