Apply about one ounce of sunscreen to cover all exposed skin 20 minutes before going outside. Sunscreen should have a SPF of at least 15 & provide protection from UVA & UVB rays. Reapply every two hours, even on cloudy days & after swimming or sweating. https://t.co/iZKOPRsSfa https://t.co/cRxZ5DHkVx — PolitiTweet.org
