Apply generously and evenly to entire face and neck 15 minutes before sun exposure. Reapply sunscreen every 2 hours. Use alone or follow with foundation.

Tip from Rose Marie, Founder of RMS : Use the two-finger method to accurately measure the amount of sunscreen needed for your face and neck. Simply apply two lines of sunscreen directly onto your index and middle fingers, from base to tip. That’s the perfect amount you need!
