Compare Pure Rayz to other equally-priced anti-aging light therapy tools and that’s the only comparison you will find – cost. Pure Rayz outshines the competitor’s tools as the most effective and powerful, anti-aging light therapy tool available without a prescription to treat wrinkles. We didn’t stop there. Designed to treat the entire face, it is FDA-cleared and offers an industry-leading, 5-year “fix or replace with no questions asked” warranty. And Pure Rayz LEDs emit only natural wavelengths of light, making it completely safe to use with over-the-counter topical products and causes no extra sun sensitivity. It is sized for portability and comes with dual-voltage power source for international usage, and is hand assembled from the highest quality ABS plastic or durability.
