A beauty editor's eureka moment: "After 20 years in the business, the only thing that ever kept me sane was my weekly aromatherapy massage," admits London-based Kathy Phillips. Following her well-educated nose, she set about developing This Works, a line of sleekly packaged, all-natural body and home products laced with delicious essential oils at levels that have been clinically proven to, well, work (true to the name). Frankincense restores, eucalyptus is antiseptic, rosemary stimulates-and then there's the nose-candy factor! Our favorites: Energy Bank Bath and Shower Oil ($60) and In the Zone Bath and Shower Gel ($35).
