The invention also relates to pharmaceutical compositions having, in addition to the acne reduction component, a skin cell conditioning component in an amount sufficient to properly regulate the keratin and sebum production of the skin cells, thereby inhibiting the appearance of acne. In a preferred form, the skin cell conditioning component is a chromium component. In another preferred form, the composition further includes at least one of a vitamin C source, burdock root, yellow dock root, horsetail extract, a catechin-based composition, a vitamin B1 source, a vitamin B2 source, a vitamin B3 source, a vitamin B5 source, and a vitamin E source. In a more preferred form, the invention also includes at least one amino acid component, a magnesium component, a selenium component, and biotin. The invention also relates to methods for treating acne by administering, alone or in conjunction with another composition, the pharmaceutical compositions in an amount therapeutically effective in reducing the incidence of acne and methods for additionally inhibiting the appearance of acne by conditioning skin cells.Other References
