Many of these formulas also contain antioxidants that prevent damage from the sun's rays and also protect the rest of your body from aging and disease.
SPF moisturizers not only protect your skin from the sun they also protect you from air pollution and other harmful environmental elements.
You'll have smoother, younger looking skin when you use a moisturizer with SPF.
My recommendation if you spend most of your day outdoors you should use a moisturizer with SPF 35 to 80.
If you don't spend a lot of time outdoors use a moisturizer with SPF 15 to 35.
Here are some of my personal recommendations, Ive used all of these and love them all... remember you don't need to spend a lot of money, these range from $10 to $30.
