Abstract

Abstract A treatment to prevent the symptoms of skin conditions characterized by an offensive odor of the body, and a treatment to alleviate the symptoms of diseases characterized by defects of keratinization consisting of the topical application of a solution, lotion, cream, ointment, powder, stick or spray containing cysteic acid, cysteinesulfinic acid, homocysteic acid or their metal chelates are disclosed. The metal chelates include molecular complexes of cysteic acid or its analogue and metal ions such as ferric, cupric, zinc and aluminum ions. The efficacious compositions may include the active ingredients present in a total amount of from 1 to 30 percent, and preferably from 2 to 10 percent by weight. In a prophylactic treatment topical application to skin areas of axilla, crotch (inguinalperineum) and feet has been found to prevent the formation of malodor. In a therapeutic treatment for the disturbed keratinization topical application to affected areas has been found to achieve a complete remission of ichthyosis, dandruff and acne.
