It may sound a little extreme, but experts often recommend a surplus of sunscreen, even at times and in places many might not consider normally. It's one thing to slap some on before you head down to the pool, for example, but what about for the ride to work or on a quick run to the grocery store? Yup, then, too.
These extreme anti-UV tactics might not be up everyone's alley, but it's a good idea to consider sunscreen as part of your daily regimen. That way, anytime you might be exposed to the sun, you'll be prepared for the onslaught of skin-ravaging rays.
Also, keep in mind that despite laudable labels and proud product claims, many sunscreens can't keep you safe all day long. They usually need to be reapplied about every two hours to maintain maximum efficiency. And for sunbathers who want a tan but manage to put on a concessionary coat of sunscreen -- that SPF 2 or SPF 4 isn't doing a heck of a lot of good. It usually takes at least an SPF 15 to keep skin healthy.
