Out of the many potential hazards to our bodies, the sun causes the largest amount of damage of your skin. In fact, it's estimated that 70 to 80 percent of skin changes, including age spots and wrinkles, come from the sun's ultraviolet rays [source: WebMD]. In order to protect your skin, it's a good idea to look for sunscreens in products that clearly list its SPF, or sun protection factor.
Dermatologists recommend that you always use a sunscreen with an SPF rating of at least 15 before going outside, even during cloudy days [source: American Academy of Dermatology]. Apply it at least 20 minutes before you go outside. Make sure that you find a good sunscreen that blocks both UVA and UVB rays, and add it to your daily skincare routine.
Many moisturizers today contain sunscreen, and some have an SPF rating of at least 15. Be sure to check the bottle to see if you need any additional protection. Most sunscreens only last about two hours. Therefore, if you apply your moisturizer in the morning and not again until bedtime, carry sunscreen with you so you can apply it during the day. If you are going to be out in the sun for long periods of time, you might want to consider moving up to an SPF of 30 to give your skin extra protection.
If you're debating whether or not to get a body moisturizer with added SPF, keep in mind that your clothes only provide an SPF level of about 3. Using an anti-aging moisturizer with sunscreen can help protect your skin and fight the signs of aging.
