Walk into any drugstore, and you’ll immediately be bombarded with an array of teeth-bleaching strips and gels, all promising to help you achieve a whiter shade of pale. If you’ve tried been less than thrilled with the standard versions, you’ll be pleased to know that there’s a new at-home option specially formulated to help you realize megawatt results. GoSmile Advanced Formula B1 ($89; gosmile.com)—named after B1, the lightest shade on the tooth-whitening chart—is rightfully being touted as quickest and safest way to obtain maximum brightening without visiting your dentist. The kit, which comes with 20 ampoules and an informational DVD, is easy to use anywhere: Just remove the glass tube from the wrapper, apply pressure until you hear a popping sound, then rub the gel on each tooth in a circular motion with your index finger twice a day. After a week, you should see four to ten levels of lift (and you'll start noticing improvements even faster). To preserve your new brightness, check out GoSmile’s Daily Compact maintenance package ($28); to freshen breath and protect against free-radical damage, try the brand's new Smileceuticals Elixer ($29); and to soothe dry lips, look no further than the Smileceuticals balm ($18)—a nourishing vanilla-flavored treatment packed with retinol, shea butter, vitamin E, and chamomile. —Ava Williams
