SEVO builds their formulas around red light therapy compatibility, which means no photosensitizing actives and nothing that fights the light. The Radiance Serum is 90% squalane and meadowfoam seed oil, with CoQ10, bakuchiol, and pterostilbene for brightening and collagen support. No retinol, no synthetic fragrance, no parabens. Also available in 30ml at $147. Manufactured in the USA.
