How is Solius different from the sun?

Sunlight is difficult to dose, varies by season and weather, and includes wavelengths that can damage the skin. Solius UVB light therapy is controlled, consistent, and personalized to your skin using an advanced sensor that ensures each dose is right for you.

The sun provides both helpful and harmful UV light. While natural sunlight triggers vitamin D production, it also includes UVA light that can damage skin and increase long-term health risks. Solius isolates only the precise UVB wavelengths proven to stimulate vitamin D production, without the excess UV radiation that causes burning, aging, or DNA damage. Solius provides the UVB light health benefits of the sun with 99% less total UV risk.
