Obagi Clinical Vitamin C Eye Brightener The Obagi Clinical Vitamin C Eye Brightener ($60) features tetrahexyldecyl ascorbate, a more stable form of vitamin C — and 90 percent of the Sephora shoppers who reviewed it would recommend it to others. That vitamin C brightens skin around the eye area, while adaptogens like rhodiola rosea support collagen and elastin production for firmer, suppler skin.
