Guerlain Spa

Waldorf Astoria’s recently introduced 90-minute Orchidée Impériale Skin Light Treatment (€230) may make you forget every rejuvenating facial you’ve ever had. It combines the Parisian beauty emporium’s famous sculpting massage with manual microdermabrasion, a fruit acid peel, and a heated sheet mask rubbed in with glass “ice bubble” rollers for radiance that’ll last through your holiday.
