Publication date: May 12, 2011
Inventors: A Yokozeki
According to the inventor of this patent, it is desirable to provide a cosmetic powder, such as in the form of a foundation, that continually conditions the skin. Thus, the current patent discloses a cosmetic composition providing skin moisturization for extended periods of time. It achieves these results by incorporating, into a powder composition, a sufficient amount of an extract of an epiphyte, sometimes called “air plant,” to speed moisturization to the skin in combination with a cosmetically or dermatologically acceptable carrier. Also described is a method for providing the extended skin moisturizing effect.
