The use of long-chain alkenones to impart desired characteristics in personal care compositions for topical applications is described. The preparation of mixtures long-chain alkenones and synthetic derivatives thereof is presented. Examples of compositions include abrasive soaps, with alkenones serving as natural exfoliating agents. Alkenones and their derivatives can serve as emollients, occlusive agents, encapsulating agents, stabilizing agents, binding agents, thickening agents, surfactants, and antimicrobials.

Disclosed is a method for moisturizing skin in need thereof, the method comprising topically applying to the skin a composition that includes effective amounts of an extract from Echinacea purpurea, an extract from Silybum marianum, and glycerin, wherein topical application of the composition activates human cannabinoid receptor type 2 and inhibits fatty acid amide hydrolase activity in the skin and treats the skin.

Provided are aqueous Alerce (Fitzroya cupressoides) cell extracts, which may be obtained from in vitro cultures of Alerce cells. The aqueous Alerce cell extracts promote cell regeneration, and therefore have anti-aging properties. The Alerce cell extracts have been found to have no toxic effects on human cells, and have been found to not boost skin cancer cells. Such extracts may be used in pharmaceutical or cosmetic formulations for skin care, especially to promote regeneration and/or anti-aging of the skin.
