Composition for the treatment of acne containing a dispersion of vesicles of ionic or non-ionic amphiphilic lipids, the vesicles containing in the lipid phase at least one salicylic acid derivative of formula (I): ##STR1## in which R represents a linear or branched C.sub.11 -C.sub.17 alkyl radical; R'.sub.1, R'.sub.2, R'.sub.3, which are identical or different, represent a C.sub.1 -C.sub.18 alkyl or hydroxyalkyl radical, it being possible for one of the radicals R'.sub.1, R'.sub.2 or R'.sub.3 to be a benzyl radical. The derivative of formula (I) serves both as charged lipid and as anti-acne active ingredient. The derivatives of formula (I) in which, when R represents a C.sub.13 -C.sub.17 alkyl radical, R'.sub.1, R'.sub.2, R'.sub.3, when they are identical, do not represent a hydroxyethyl radical.
含有离子或非离子两性脂质囊泡分散体的治疗痤疮组合物,该囊泡中的脂质相含有至少一种式(I)的水杨酸衍生物:##STR1## 其中R代表线性或支链C.sub.11-C.sub.17烷基基团;R'.sub.1,R'.sub.2,R'.sub.3相同或不同,代表C.sub.1-C.sub.18烷基或羟基烷基基团,其中可能有一个基团R'.sub.1,R'.sub.2或R'.sub.3是苄基基团。式(I)的衍生物既可作为带电的脂质,又可作为抗痤疮活性成分。当R代表C.sub.13-C.sub.17烷基基团时,当R'.sub.1,R'.sub.2,R'.sub.3相同时,它们不代表羟乙基基团的式(I)的衍生物。
