Topical compositions intended for skin treatment and based on salicylic acid derivatives. The invention relates to topical compositions with a keratolytic and/or comedolytic effect, containing, in a carrier which is suitable for application to skin, at least one compound corresponding to the formula I: ##STR1## in which R denotes a linear, branched or cyclized saturated aliphatic chain containing from 3 to 11 carbon atoms, an unsaturated chain containing from 3 to 17 carbon atoms and containing one or more conjugated or unconjugated double bonds, these various substituents being optionally substituted by one or more halogen atoms, by one or more trifluoromethyl groups, by one or more hydroxyl groups in free form or esterified with an acid containing from 1 to 6 carbon atoms or by a carbonyl group which is free or esterified with a lower alcohol containing from 1 to 6 carbon atoms, R' denotes a hydroxyl group or an ester group of formula: ##STR2## where R.sub.1 denotes a saturated or unsaturated aliphatic group containing from 1 to 18 carbon atoms.
用于皮肤治疗的局部组合物,基于水杨酸衍生物。该发明涉及具有角质溶解和/或丙痘作用的局部组合物,其包含在适合涂抹于皮肤的载体中,至少含有一种符合以下式I的化合物:##STR1## 其中R表示含有3至11个碳原子的线性、分支或环化饱和脂肪链,含有3至17个碳原子的不饱和链并含有一个或多个共轭或非共轭双键,这些不同的取代基可以选择地被一个或多个卤素原子、一个或多个三氟甲基基团、一个或多个游离形式的羟基或与含有1至6个碳原子的酸酯化的羟基或一个自由或与含有1至6个碳原子的低级醇酯化的羰基基团取代,R'表示一个羟基或一个具有以下式的酯基团:##STR2## 其中R.sub.1表示含有1至18个碳原子的饱和或不饱和脂肪族基。
