The device is designed to reduce swelling and ease nasal breathing by targeting inflammatory processes in the sinus area. As swelling decreases, the nasal passages become more open, which may help restore natural breathing through the nose.

The operating principle of the red light nasal therapy device is based on the targeted application of light radiation to the sinus area. The light penetrates the tissues and interacts with cells, including mitochondria, which may support cellular energy processes. As a result, inflammation may be reduced and the natural cleansing processes of the nasal passages may improve.

The device emits red light with a wavelength of 660 nm — a narrow-band wavelength designed to penetrate the nasal passages. This range is used to affect the nasal mucosa and, with regular use, may help reduce inflammation, improve mucus drainage, and relieve nasal congestion.
