Encouraged to open her own studio after twelve years in the business, recruited by posh hotels, and currently working out of The Spa at Four Seasons, Hannah is popular among the Hollywood scene. Actress Winona Ryder sees her regularly when in town. Hannah is known for her use of the IDERM machine, which utilizes galvanic ionization. We'll admit that the procedure feels slightly odd at first. The face is wrapped in cloth, a lightweight mask is placed on top, and then electrical currents are gently applied. When complete, our skin felt clean and firm. The best thing was the absent post-blotchiness or redness typical of facials. We also appreciated the cleanliness of Hannah's technique and the lack of metal tool extractions.
