How is Solius different from the sun?

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 benefits of the sun with less than 1% of the total UV light risk. It is controlled, consistent, and personalized for your skin type using an advanced skin sensor to ensure each dose is right for you. Sunlight is difficult to dose, varies by season and weather, and includes wavelengths that can damage the skin.
