Like shopping at Wet Seal, eating Fruity Pebbles, and riding a merry-go-round, there are some pleasures that, while admittedly designed for the younger crowd, are deliciously fun to steal. And Tess--a new line that stands for "Teen Everyday Skincare System"--yields such fabulous results that it simply can't be left to the under-age set. The brand's Almost Normal Skin Kit ($48; sephora.com) comes in a portable carrying case, perfect for tossing in an overnight or gym bag (or keeping at a special friend's house for spontaneous slumber parties). Inside, the six numbered products guide you through a solid facial routine, no "eenie-meenie" necessary; plus, they're all paraben-free and formulated with natural fruit and botanical extracts.

The Rise and Shine Strawberry/Jojoba Facial Cleanser smells delicious and provides gentle exfoliation, while the Ooh-Refreshing Apple Toner purifies skin without stinging or making you smell like a liquor cabinet. For day, the Out and About SPF 15 Lavender Oil-Free Lotion comes in a handy spritz formula that will convince even the most reluctant to use sun protection; and after the sun goes down, the Time for Some Zzzs Vanilla Night Time Moisturizer is ideal for combination skin that's not quite ready for heavy wrinkle creams. My favorite product in the kit, the Zip It Peppermint Blemish Stick, goes on clear and undetectable, and kept my face problem-free, even during that dicey-complexion time of the month. And the strawberry on top is the Perfect Pout Healing Lip Gloss--killer shine, no stick, and good for your lips to boot. My recommendation? Put Tess on your list of things to swipe from your lil' sis (it'll look so much better on you than her Nick Lachey concert tee). --Zoe Stagg
