  • Patent number: 6638543
    Abstract: Many human conditions, often skin conditions, are treated topically or orally with a retinoid such as retinoic acid or acetretin, which treatment often has the side effect of dry, irritated, and/or peeling skin. The use of soaps, detergents, chemical irritants, and such can also cause these same side effects. These side effects can be reduced or eliminated by the topical administration of an inhibitor, especially a natural inhibitor, of the epidermal growth factor receptor (EGFR), administered concomitantly with the retinoid, separately from the retinoid (such as on an as needed basis), or both. Administration of the two together is facilitated by a composition suitable for topical application and comprising both the retinoid and a natural EGFR inhibitor. Preferred natural inhibitors are genistein and other isoflavones extracted from natural occurring substances, or simple derivatives of such substances.

  • Patent number: 6352724
    Abstract: A method for the topical treatment of skin affected with acne, rosacea, or a combination thereof. Sodium chloride in a substantially pure form is topically applied to the affected skin by gently gliding the sodium chloride over the affected skin in a manner insufficient to cause abrasion and debridement of the affected skin. A solid block of about 98% to about 100% by weight sodium chloride free of a carrier and/or free of other topical acne-treatment medicaments and/or free of other topical rosacea-treatment medicaments should be used. The applied sodium chloride is left on the skin. Preferably, the affected skin is pre-moistened with water from shaving, bathing, splashing water on the skin, and the like prior to gliding the sodium chloride thereon.
