Acne is treated or prevented by the topical application of compositions containing an alkanolamine such as dimethylaminoethanol, tyrosine, and a sulfur ingredient such as lipoic acid or glutathione. Adjunct ingredients such as fatty acid esters of ascorbic acid, e.g., ascorbyl palmitate and .alpha.-hydroxy acids may be included in the formulations. Compositions of the invention may be used alone, or, in many preferable embodiments, in combination with conventional acne medications such as anti-acne products containing salicylic acid, benzoyl peroxide, or a retinoid. In these embodiments, alkanolamine compositions of the invention are applied to affected skin areas first, and then a conventional acne medication is applied. This maximizes the efficacy of the treatment while minimizing skin irritation caused by conventional medications.

Treatment of acne using alkonolamine compositions

Active acne and acneiform scars are treated by topical application of a composition containing lipoic acid and/or a lipoic acid derivative such as dihydrolipoic acid, a lipoic or dihydrolipoic acid ester, a lipoic or dihydrolipoic acid amide, a lipoic or dihydrolipoic acid salt, and mixtures of any of these to reduce erythema, pore size, and scarring. Topical application of lipoic acid and/or a lipoic acid derivatives are advantageously used with at least one adjunct ingredient such as a retinoid, an antibiotic, or benzoyl peroxide conventionally used for acne, alone or in combination with dimethylaminoalcohol, an .alpha.-hydroxy acid such as glycolic acid, a tyrosine, tocotrienol, and/or a fatty acid ester of ascorbic acid. One preferred embodiment contains a combination of lipoic acid, an .alpha.-hydroxy acid, and dimethylaminoalcohol.

Composition of a water-soluble sunscreen preparation for acne rosacea

This invention relates to Schiff's bases derived from amino acids and hydroxyaryl alkyl ketones, or a plant extract containing the same, having general chemical structure in FIG. 1 for topical application. This invention also relates to certain metal complex of said Schiff's bases, which have a crown-like appearance in their three-dimensional chemical structure, as in FIG. 2. The Schiff's bases and their metal complexes of the present invention are useful for the modulation of metal-activated enzymes and metalloenzymes, such as Phenylalanine Hydroxylase, Tyrosine Transaminase, Phenylalanine Transaminase, Tyrosinase, various MMP (Matrix metalloproteases), Superoxide dismutase, 5-Alpha Reductase, and citrate lyase. These are further suitable for multifunctional topical methods for skin whitening, skin wrinkles reduction, skin antiaging, collagen synthesis, acne control, hair loss prevention, hair graying control, and facial oil control.
