In general, it is recommended to apply a nickel-sized amount of sunscreen to the entire face daily. If you are at the beach or pool or in direct sunlight, it is recommended to apply 1 shot glass amount of sunscreen to the entire exposed skin. In general, the sun’s rays are strongest typically around 10am to 4pm and so it is recommended to be diligent about SPF and sun protection for the face during this time of day . A helpful tip: When your shadow is shorter than you are….seek shade!
