Clinically validated on-device app delivers smartphone-level simplicity with built-in safety controls 

CLEVELAND, March 9, 2026 /PRNewswire/ -- Phothera, the leading manufacturer of FDA-cleared light therapy devices for chronic skin conditions including vitiligo, psoriasis, atopic dermatitis, and cutaneous T-cell lymphoma (CTCL), today announced the availability of Guided Mode, a next-generation on-device app designed to simplify and standardize home phototherapy.

Guided Mode integrates AAD guideline-based treatment protocols directly into the device, providing step-by-step guidance and safety guardrails to support consistent, physician-directed treatment at home. This feature is supported by evidence from the ~800 patient Light Treatment Effectiveness (LITE) Study, published in JAMA Dermatology, which validated the safety and effectiveness of home phototherapy in a large clinical cohort. "Guided Mode brings smartphone level simplicity to home phototherapy," said Padma Sundar, Chief Commercial Officer at Phothera. "It's intuitive by design and utilizes AAD-standard protocols to guide every treatment session. Patients who received guided-mode based home light therapy had three times better adherence to treatment than those receiving in-office treatment".

Home phototherapy is supported by extensive clinical evidence across multiple chronic dermatologic conditions. Guided Mode builds on that foundation with a digitally enabled experience designed to improve usability while maintaining clinical oversight. Dr. Raja Sivamani, board-certified dermatologist at Pacific Skin Institute added: "I am pleased by this continued commitment to phototherapy and that patients can now be offered home phototherapy with even greater confidence. With Guided Mode, I am confident in the greater safety in dosing and ease of use for patients."

Phothera's portfolio includes both in-office and home phototherapy systems engineered to expand access to evidence-based light therapy. Phothera remains committed to advancing patient-centered innovation that bridges the gap between clinical care and the home environment.
