Apply 30 minutes before exposure and reapply frequently and generously every two hours to maintain protection, especially after swimming, perspiring or towelling. Caution: Overexposure to the sun is dangerous. Avoid exposure to the sun during the hottest hours of the day, even while using a sunscreen product because it does not provide you 100% protection. Keep babies and children under 3 out of direct sunlight. For medical conditions seek advice from your GP.
