Allure magazine plans to launch this fall a spa-oriented offshoot publication called Allure Spa. Billed as a guide to the luxury spa experience, Allure Spa will cover skin care, fitness, fashion, nutrition and lifestyle trends at destination and day spas. The magazine also will explore hotel and resort spas, as well as medi-spas, and aims to tap industry experts to present consumers with an insider point of view. Allure editor in chief Linda Wells also will be in charge of Allure Spa. Allure is owned by Condé Nast Publications, parent of WWD.
