The Dusa Blu-U Light Model 4170-1 is a professional-grade Blue Light Photodynamic Therapy system designed for the treatment of moderate inflammatory acne and specific dermatological conditions. Built with a durable sheet-metal chassis and seven horizontally mounted U-shaped fluorescent tubes, the Blu-U delivers consistent, high-intensity blue light while maintaining patient safety through its protective polycarbonate shield.
Mounted on an adjustable floor stand with 3-axis positioning, the Blu-U ensures fast and precise patient alignment, making it an ideal device for dermatology clinics, cosmetic centers, and medical practices offering non-invasive skin therapies.
Advanced Blue Light Therapy
The Dusa Blu-U emits targeted blue light at 417 nm, a wavelength shown to effectively address moderate inflammatory acne by destroying acne-causing P. acnes bacteria. This helps reduce inflammation, minimize active breakouts, and support clearer, healthier skin.
Versatile Dermatology Applications
Beyond acne, the Blu-U is also widely used in the treatment of actinic keratosis when paired with approved photosensitizing agents. Its controlled illumination makes it a reliable option for practices seeking proven, non-invasive dermatological solutions.
Safe, Non-Invasive & Patient Friendly
The BLU-U system delivers treatment without pain, chemicals, or needles. The polycarbonate shield prevents accidental contact, and its cooling airflow system keeps patients comfortable throughout therapy.
