Assignee: Mary Kay Inc.
This invention relates to a method for reducing the appearance of fine lines or wrinkles on skin, and other conditions, by topically applying a composition including glyceryl di-salicylate and glyceryl mono-salicylate compounds. Non-limiting examples of skin conditions include spider veins, melasma, blotches, sun damage, dermatitis, rosacea, acne, impetigo, eczema and other inflammatory skin conditions.

Caftaric acid to regulate skin pigmentation
US Patent Application 20130101556
Publication date: April 25, 2013
Assignee: L'Oréal and Nestec S.A.
Disclosed in this patent is an ingredient containing caftaric acid and/or derivatives for preventing and/or treating hyper-pigmentation of skin, skin color imperfections such as age-spots, and other skin disorders characterized by abnormal pigment. According to the inventors, various compounds intended for these effects, when applied topically, are capable of reducing tyrosinase activity and limiting melanin production but are not entirely satisfactory, in terms of irritant side effects. Alternative preparations are therefore desired that do not have these drawbacks; in particular, nutritional cosmetic compositions administered via an oral route that have improved stability and efficacy.
The present inventors reportedly achieve this objective by providing a food supplement composition that includes at least one ingredient containing caftaric acid and/or derivatives. In addition, combinations of treatment with, optionally, oral or topical forms may be envisaged in order to supplement or reinforce the activity of the ingredients as defined by the invention.
