GET YOURSELF COVERED: OK, we know the weather's been kinda uneven lately. But even when it's cool out, you need to protect your skin. Mix it up with the Sephora Sun Safety Kit ($25), which brings together scads of trial-sized sun protection goodies. The set includes Murad Essential-C Eye Cream SPF 15, Jack Black Intense Therapy Lip Balm SPF 25 and two single-use UVSunSense UV monitoring bracelets, plus four other trial-size items. It all comes in a pink Sephora makeup bag. Even better, 100 of proceeds go to the Skin Cancer Foundation. GET IT: Sephora, 3065 M St. N.W., Pentagon City and others.
