Dermatologists suggest that folks reapply sunscreen each 2 hours to make sure full safety. Papadeas says, in his family, they purchase new sunscreen merchandise every season, since “the chemical substances change into weaker” and are much less efficient over time. So, search for the expiration date, or higher but, restock with new merchandise at the start of summer time.
4 Cloudy days can result in sunburns
