As the summer season approaches and many of us head outside to bask in the sun, what sorts of myths have we been telling ourselves about the best ways to protect our skin from the sun? Is 100 SPF really necessary? How long can you be outside before the sun starts to damage your skin? Do you only need sunscreen in the summer? How much is enough sunscreen to put on your skin?
