A method for protecting the skin against UV rays uses at least two cosmetic skincare and/or make-up compositions, and comprises applying a first layer of a first cosmetic composition comprising an oil phase and, optionally, an aqueous phase, followed by applying, on the first layer, a second layer of a second anhydrous composition comprising at least 70 wt.-% powders selected from among fillers and pigments, and an oil phase. At least one of the two compositions contains at least one UV filter, preferably a liposoluble UV filter. The first composition may be a make-up foundation or skincare base. The second composition may be a loose or compact powder.
