The invention relates to a cosmetic composition, in particular in the form of a liquid cosmetic composition, comprising in a physiological medium (i) at least a plate type filler with refractive index>1.6 and having a particle size between 1 μm and 20 μm, preferably between 1 μm and 15 μm, (ii) at least a silicon elastomer, preferably a non-emulsifying silicon elastomer, and (iii) at least a filler having an oil absorption capacity greater than or equal to 1 ml/g. The composition is preferably used as a skin care or make-up base or primer intended to decrease the visibility of skin imperfections, in particular the pores and make the pore hiding effect long lasting.
