A smarter, safer way to stimulate the UVB health benefits of the sun is finally here. Solius is the only FDA-cleared over-the-counter UVB light therapy device that analyzes your unique skin tone to deliver a precise, optimal dose of UVB light, activating the natural health benefits of the sun with less than 1% of the total UV risk. The Solius app pairs with a Solius device, which is required for use and is sold separately at solius.com. PERSONALIZED DOSING FOR YOUR SKIN Solius scans your skin with a built-in sensor and automatically calculates a dose designed for your unique tone, so every session delivers an optimal dose of UVB light therapy. FDA-CLEARED, NO PRESCRIPTION NEEDED Solius is the only UVB light therapy device cleared by the FDA for over-the-counter use, reviewed under the Class II medical device pathway for safety, performance, and quality. APPROXIMATELY FIVE MINUTES, ONCE A WEEK A single short session, once per week, is designed to maintain the UVB light-driven benefits your body relies on year round, regardless of season, weather, or where you live. GUIDED SESSION FLOW Step-by-step in-app guidance walks you through positioning, session length, and safety checks to ensure you get the full benefit of each dose without guesswork. STREAKS AND WEEKLY REMINDERS Smart reminders nudge you when it's time for your next dose. Weekly streaks and progress views help consistency turn into results and whole body benefits. THERAPY HISTORY AND TRENDS Review every session at a glance: date, duration, dose, and therapy timespan. SAFETY The Solius dosing sensor calculates an optimal safe dose. A full year of weekly Solius therapy adds up to less total UV than about five minutes of natural midday sun. HOW IT WORKS 1. Download the Solius app and create an account, allowing you to pair with your Bluetooth® connected Solius device to complete set up and control your device. 2. Set up anytime, anywhere: Solius is easy to set up, no mounting or installation required. 3. Personalize your dose: The Solius app guides you through smart skin analysis to calculate your optimal dose. 4. Repeat therapy weekly: Use Solius for approximately five minutes a week to maximize year-round benefits.
