Apply before skin is exposed to sun. Shake well before use, turn the bottle upside down so that no extra gas escapes. A handful of mousse is sufficient for protection of an adult arm. Work the mousse into a more liquid consistency between your hands. Spread evenly and generously over the skin. Wait a few minutes until the mousse is dry before bathing or putting on clothes. Should be non-sticky after 10 minutes. The bottle provides approximately 10 full body applications for an average-sized adult. Insufficient quantity will significantly reduce the protection provided. Apply frequently on exposed areas and avoid contact with eyes. Reapply frequently
