Abstract: The present invention relates to a composition, in particular a cosmetic or dermatological composition, comprising: a) at least one merocyanine compound corresponding to formula (3) below, and also the geometric isomer forms, in particular E/E or E/Z geometric isomer forms, thereof: wherein: A is —O— or —NH—; R is a C1-C22 alkyl group, a C2-C22 alkenyl group, a C2-C22 alkynyl group, a C3-C22 cycloalkyl group or a C3-C22 cycloalkenyl group, it being possible for said groups to be interrupted by one or more O; and b) dipropylene glycol. The present invention also relates to a non-therapeutic cosmetic process for caring for and/or making up a keratin material, comprising the application, to the surface of said keratin material, of at least one composition as defined above.
