The present invention relates to an oil-in-water emulsion with globules of oil, the number-average size of which is less than or equal to 200.0 nm, comprising: a) a continuous aqueous phase, b) an oily phase dispersed in said aqueous phase, c) a mixture of nonionic surfactants comprising: (i) at least one alkoxylated fatty ester, and (ii) at least one fatty ester of glycerol, d) at least one anionic amphiphilic lipid, e) at least one liposoluble organic UV-screening agent, characterized in that it does not comprise any monoalcohol comprising from 2 to 8 carbon atoms, and that the weight ratio of the amount of oily phase to the total amount of nonionic surfactants and anionic amphiphilic lipid is from 2 to 20. The invention also relates to a cosmetic process for limiting the darkening of the skin and/or improving the colour and/or uniformity of the complexion, comprising the application, to the surface of the keratin material, of a composition as defined previously. It also relates to a cosmetic process for preventing and/or treating the signs of ageing of a keratin material, comprising the application, to the surface of the keratin material, of a composition as defined previously. It also relates to a cosmetic process for moisturizing a keratin material, comprising the application, to the surface of the keratin material, of a composition as defined previously.La présente invention concerne une émulsion dhuile-dans-leau ayant des globules dhuile, dont la taille moyenne en nombre est inférieure ou égale à 200,0 nm, comprenant : a) une phase aqueuse continue, b) une phase huileuse dispersée dans ladite phase aqueuse, c) un mélange de tensioactifs non-ioniques comprenant : (i) au moins un ester gras alcoxylé, et (ii) au moins un ester gras de glycérol, d) au moins un lipide amphiphile anionique, e) au moins un agent de filtrage UV organique liposoluble, caractérisée par le fait quelle ne comprend aucun monoalcool comprenant de 2 à 8 atomes de carbone, et par le fait que
