Overview
Up to 90% of skin aging is caused by UV light from the sun. Most of this is caused by UVA light and only two FDA-approved chemical ingredients protect against it, one of which is neither photostable nor GRASE. To address this, we have developed a patented, photostable, and safe ingredient that can dramatically increase current UVA protection.
