Personalized dosing

The first and only light therapy panel that analyzes your skin and automatically calibrates a personalized dose to deliver safe sun for every skin tone.

Clinically proven

Independent research from Boston University showed Solius provided a significant 10.2 ng/mL increase in vitamin D, with participants demonstrating a mean individual percent change of 76% from their baseline level. (Anticancer Research; DOI: 10.21873/anticanres.17693)

FDA-cleared

Solius is FDA-cleared as a Class II medical device, which confirms that Solius meets rigorous safety, performance, and quality standards. Solius is the only UVB light therapy device cleared for over-the-counter use without a prescription.

Quick weekly therapy

Approximately five minutes, once a week, is all it takes to support the sunlight-driven benefits your body needs, year round.

Safe sun technology

Solius’s precision sunlight technology is designed to provide the benefits of UVB light exposure with minimal ultraviolet radiation (UVR). A full year of Solius therapy is the same UVR exposure as approximately five minutes of midday sun.

Novel UVB light spectrum

The most advanced medical-grade UVB LEDs with breakthrough technology that safely and precisely target the UVB action spectrum, while nearly eliminating damaging UVA exposure.
