Actress Alison Sweeney may be known for her longtime role as the oft-scheming Sami Brady on Days of Our Lives, as well as for her hosting gig on The Biggest Loser. But she also has one of the clearest, smoothest complexions on TV — and with good reason. "My mom was an advocate of healthy skin and sunscreen before it was fashionable," says Alison, who recently helped select the finalists for a modern-day Coppertone girl contest.

And while Alison reveals she doesn't have any special skin care rituals in particular, she does follow the same regimen each day: sunscreen (Coppertone's Oil Free Faces SPF 30) in the morning and a liberal application of moisturizer in the evening. If she could travel back and tell her 20-year-old self what to change, though, it would involve being more diligent with cleansing. "I wish I had known how important it is to wash your face every night before going to bed and remove all traces of makeup," she says. Sound advice for saving face.

If you take your sun protection seriously, here's just the app for you: Coppertone MyUVAlert. Even if you're not quite as diligent about SPF, you'll at least take away some sage advice from this application.

Just type in your zip code, or the zip of any other US city, and you'll get the current UV index, along with advice on what to do to protect yourself based on the reading. You can then customize by activity levels to receive product recommendations (Coppertone, of course). You can even set a timer to remind you to reapply your SPF at regular intervals. FYI: Every two hours or so is the standard.

There's even a tips section chock-full of helpful words of SPF wisdom, and a link to the Weather Channel website. Will this app blow your mind? No, but I could see it coming in handy at the store or while on vacation. And since it's free, and you get a $1 off coupon just for downloading, it's worth a few minutes of your time to check out.
