Dr Barbara Sturm is responsible for some of Hollywood’s most luminous complexions—Rosie Huntington-Whiteley, Hailey Baldwin and Kim Kardashian to namedrop a few—and lately she’s been getting almost as much press as her celebrity clients. That would be because of Sturm’s collection of “molecular cosmetics”, which recently arrived at Mecca Cosmetica. The Dusseldorf-based doctor takes a minimalist approach to skin care with a tightly-edited selection of essentials based on her scientific expertise (she began her career as a surgeon). The line-up focuses on botanical-based formulas and innovative ingredients that aim to heal the skin, reduce inflammation and activate the now famous #STURMGLOW. Press play to see exactly what she prescribes—including the hydrating mask worn by Allison Janney on Oscar night.
