The present invention relates to a cosmetic or dermatological composition in the form of a water-in-oil emulsion comprising, in a physiologically acceptable support: a) at least one aqueous phase, and b) at least one oily phase, and c) at least one merocyanine compound of formula (1 ) or one of the E/E- or E/Z- geometrical isomer forms thereof formula (1) in which 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 the said groups to be interrupted with one or more O and d) at least one emulsifying system comprising at least one emulsifying polymer of the polyoxyalkylenated glycol fatty acid ester type. The invention also relates to a non-therapeutic cosmetic process for caring for and/or making up a keratin material, consisting in applying, to the surface of the said keratin material, at least one composition according to the invention as defined above. The invention also relates to a non-therapeutic cosmetic process for limiting the darkening of the skin, improving the colour and/or uniformity of the complexion, comprising at least the application, to the surface of the keratin material, at least one composition as defined previously. The invention also relates to a non-therapeutic cosmetic process for treating the ageing of a keratin material, comprising at least the application, to the surface of the keratin material, at least one composition as defined previously.
