Maria Hatzistefanis

London-based beauty entrepreneur Maria Hatzistefanis started her career as a beauty writer before moving to New York where she received an MBA from Columbia Business School. She founded her ground-breaking skincare group, Rodial, in 1999 by identifying a niche for treatments targeted to specific skin concerns, with evocative tongue-in-cheek names such as Snake Serum and Dragon's Blood. Maria now runs two brands—Rodial and Nip + Fab. She has been profiled in Forbes and Vanity Fair, and appeared as a guest on Project Runway.
