ABSTRACT
In 1980, Albert Kligman recognized that even water could alter the structure and function of skin and coined the term cosmeceutical to indicate a topical substance that is sold as a cosmetic product but has performance characteristics that suggest pharmaceutical action (Elsner and Maibach, 2005). Cosmeceuticals are cosmetic products that have drug-like properties and enhance or protect the functional appearance or order of the human body, which include antiphotoaging and photoprotective creams, moisturizers, lotions, shampoos, etc. These represent a category of products placed between nonprescription and prescription products that treat various topical diseases (Amer and Maged, 2009). However, the results of these treatments are sometimes disappointing, creating a need for more effective and safer agents that are less irritating. Presently, there is a universal trend not only favoring natural treatments of various skin diseases but also enhancing human beauty by means of photoprotection.
