After you've got your head ready to accept the moisturizer - cleanse twice a day. And moisturize once a day. Usually before put your make up on. Always use a moisturizer with SPF, you've gotta protect your skin from the sun's harmful rays!
I recommend using a Sensitive Skin cleanser and moisturizer regardless of your skin type, at least at first. If you're new to cleansing and using moisturizer, try using Cetaphil, it's on the affordable side, and it's really good stuff!
