Use of compositions in the form of emulsions containing alpha -hydroxy and beta -hydroxycarboxylic acids, along with one o more glucose- and oligoglyceride-based surfactants, for cleansing skin and for the treatment of acne, is new. The use of certain cosmetic and/or dermatological compositions in emulsion form is claimed for cleansing the skin or treati acne. The compositions comprise: (1) one or more alpha -hydroxycarboxylic acid derivatives of formula (R')(R'')(OH)C-COOH (I) and/or one or more beta -hydroxycarboxylic acid derivatives of formula (R')(R'')(OH)C-X-COOH (II); (2) one or more surfactants A based on glucose derivatives of formula (III); and optionally (3) one or more other surfactants B of formula R3-O-(CH2-CH(OR4)-CH2-O)n-R5 (IV). X = an aliphatic CH2 group, a cycloaliphatic CH group, an aromatic CH group or a CH(OH) group; R', R'' = H, 1-25C alkyl (optionally substituted by one or more COOH, OH, aldehyde or oxo groups), phenyl (optionally substituted by one or more COOH, OH or 1-25C alkyl groups), or the alpha - or beta -carbon atom forms 3-7C cycloalkyl together with R' and (optionally substituted by one or more COOH, OH, oxo or 1-25C alkyl groups); R = 1-24C alkyl; R1 = H or 1-24C alkyl; R2 = H or 1-24C acyl; R3-R5 = H, 8-24C fatty acid (which may be substituted by up to 3 OH groups); n = 2-8.
