The invention relates to cosmetic preparations, comprising an outer flowable gel-type phase on an aqueous basis, which is provided with a transmission for light of the wavelength 700 nm from the range of 30 to 100%, and/or which has a viscosity selected from the interval of 1000 to 10000 mPas at a temperature of 25°C and a shear rate of about 10, preferably of 3000 to 9000 at a temperature of 25°C and a shear rate of about 10, in particular preferably of 5000 to 8000 at a temperature of 25°C and a shear rate of about 10, and which, optionally, contains conventional water-soluble or dispersible auxiliary agents and or additives; an inner solid particulate phase, which comprises substantially spherical particles, whose average diameter is selected from the range of 0.1 to 10 mm, preferably 2 to 7.5 mm. The particulate phase comprises a polymer matrix that is substantially insoluble in water, one or more substances selected from the group of ubiquinones and/or plastoquinones, one or more light-filter substances, which is selected, or are selected, from the group of metal oxide pigments, optionally one or more light-filter substances, which is, or which are, selected from the group of the conventional cosmetic light-protective filter substances.
