For initial application, pump brush three times to release minerals and tap brush once or twice to evenly distribute minerals. Once set-up, there is no need to pump the brush again as doing so will clog the brush. 15-30 minutes prior to sun exposure, sweep the brush with gentle semi-circular strokes over the skin and apply a thin layer of minerals; continue for more opaque coverage. For best results, apply after moisturizer has completely absorbed into the skin. Reapply at least every 2 hours or reapply after 40 minutes of swimming or sweating and immediately after towel drying.
