“Phototherapy is essential in the treatment of vitiligo. The development of the Guided Mode controller optimizes the safety and efficacy of home phototherapy.”

— Dr. Amit G. Pandya, MD, Dermatologist

Technology That Keeps Patients on Track

In the LITE Study—the largest randomized controlled trial of home phototherapy to date—Guided Mode technology was instrumental in improving patient adherence. By prompting patients to report skin response and automatically adjusting treatment doses, Guided Mode made therapy safer, easier to follow, and more consistent. These improvements led to higher treatment completion rates and better long-term outcomes across diverse patient populations.
