Zerigo Health is a private San Diego-based medical device company focused on developing innovative technology, products, and services that improve care for people with chronic skin conditions. The Clarify System, cleared by FDA in 2017, is indicated for localized phototherapeutic treatment of dermatologic conditions such as psoriasis, vitiligo, atopic dermatitis (eczema), seborrheic dermatitis and leukoderma on all skin types (I-VI). It is the first and only connected phototherapy system that uses an app on the patient’s own smartphone (iOS or Android) to manage the dose, frequency, and duration of UVB light therapy, helping to ensure that patients receive the proper doses recommended by the American Academy of Dermatology and Vitiligo Working Group. The treatment regimen is prescribed by the patient’s physician but monitored and controlled by the Clarify System, enabling patients to administer treatment with clinical precision in the convenience of their homes. The connected system monitors dosing, adherence, compliance, patient progress and satisfaction.
