The invention concerns compounds of formula (I) in which: Ar represents a radical selected among formulae (a) to (c). Z being O, S, or N-R6; R1 represents in particular a halogen atom, -CH3, or carboxyl; R2 and R3 represent in particular H, alkyl, cycloalkyl; or R2 and R3 together form a cycle with 5 or 6 chains; R4 and R5 represent in particular H or a halogen atom; R6 represents in particular H or alkyl; X represents a radical Y-CC-; Y represents O, S(O)n or Se(O)n', n being 0, 1 or 2, and the salts of the compounds of formula (I). Said compounds can be used in particular for treating dermatological diseases related to keratinization disorder, and to fight against skin ageing.
