For first time application, pump brush three times to release minerals and tap brush one or two times to evenly spread minerals. Once set-up, don't pump the brush again as doing so may clog the brush. 15-30 minutes before exposure to the sun, gently sweep the brush with semi-circular strokes over the skin and administer a thin layer of minerals; continue for more opaque coverage. For the best results, apply after moisturizer has totally absorbed into the skin. Apply again at least every 2 hours or after 40 minutes of swimming or sweating and at once after towel drying.
