An aromatic polycyclic compound has the formula STR1 wherein R represents --SO3 H, SO2 NHR3, STR2 --SO2 R3, --SOR3 or --SR3, R3 represents lower alkyl, monohydroxyalkyl, polyhydroxyalkyl, aminoalkyl, carboxyalkyl, aminocarboxyalkyl or alkoxyalkyl, R' represents hydrogen, lower alkyl, lower alkoxy, hydroxy, C1 -C4 acyloxy or amino, R" represents hydrogen, lower alkyl or lower alkoxy, or R' and R", taken together, form an oxo, methano or hydroxyimino radical, R1 represents hydrogen or lower alkyl, n is 0 or 1, when n=1, R2 represents hydrogen or lower alkyl, or R1 and R2, taken together form a vinylene radical, and Ar represents an aromatic radical selected from STR3 wherein R4, R5, R6, R7, R8, R9, R10 and R11 represent hydrogen or lower alkyl, at least one of R4 and/or R5 being other than hydrogen, and at least two of R8 -R11 being other than hydrogen, A represents methylene or dimethylene substituted or not by lower alkyl; when A represents dimethylene, R8 and R10 together can form a methylene or dimethylene radical, and the salts of the compound of formula I as well as their geometric and optical isomers. These compounds are useful in human and veterinary medicines and in cosmetic compositions.
