Guerlain equals glamour. And there's no shortage of it at the Hôtel de Crillon's petite, recently opened spa, designed by Sybille de Margerie with three lilac treatment rooms. As befits an 18th-century palace hotel filled with gilt Louis XV antiques, the Guerlain Beauty Institute focuses on classic French beauty techniques. Soft towels infused with Eau de Cologne Impérial finish off the body treatment; the Ultimate Relaxing Facial with Guerlain's Issima line is the perfect prelude to a makeup lesson with the renowned Olivier Échaudemaison. Now you're ready for the runway. Guerlain Beauty Institute, Hôtel de Crillon, 10 Place de la Concorde, Paris; 800/223-6800 or 33-1/40-07-90-44.
