Breaking down these medical treatments one step further, UVB light therapy may use fluorescent bulb technology or LED light technology. Ongoing innovation has enabled delivery of narrow spectrum UVB light treatments using LED technology for optimal results.

UVB light therapy is recommended to improve or treat a host of medical conditions, including:

Vitiligo: a skin disorder in which smooth, white areas/patches appear on the skin, most commonly affecting the hands, forearms, feet and face

Psoriasis: a chronic skin disease that manifests as red scaly plaques commonly found on the elbows, knees, and scalp. In psoriasis, the skin cells turn over too quickly. UVB penetrates the skin and slows the growth of affected skin cells that are turning over too quickly

Seasonal depression: a mental condition that occurs when there is less sunlight at certain times of the year. Symptoms present as fatigue, depression, hopelessness, and social withdrawal

Alopecia areata: an autoimmune disorder that often results in unpredictable hair loss in a concentrated part of the body

Vitamin D deficiency: vitamin D3 is a hormone naturally produced by sun to skin contact. Levels of vitamin D are managed by several internal control mechanisms to ensure the body gets only what it needs. Lack of UVB exposure means the body can’t absorb necessary light to produce vitamin D, which supports immune system health. Deficiency in vitamin D leads to weakened immune responses
