The most important step you can take to protect your skin is to apply a sunscreen everyday. Use at least an SPF 10 to your face and exposed areas of your body whenever you are going to be out in the sun. Many moisturizers contain SPF 10-15 sunscreen, or you may wish apply a separate product that is specifically a sunscreen with a higher SPF level. Whichever option you choose, make sure you buy a sunscreen suitable for your skin type.
