Our review

Restore the look of skin radiance in just 7 days* with cult-favorite C-Tetra. Formulated with a stabilized form of vitamin C (7%) called tetrahexyldecyl ascorbate, this lightweight serum works to visibly brighten uneven skin tone and reduce the look of fine lines and wrinkles, while remaining gentle on sensitive skin. Fortified with vitamin E, this antioxidant powerhouse also helps to promote a more youthful and healthy-looking complexion overall. The perfect option for those who are new to vitamin C, or those with sensitive skin.
