Xanthophyll

goodie
Also-called-like-this: Lutein
What-it-does: antioxidant

Details

A fat-soluble carotenoid pigment that can be found in dark green vegetables such as spinach, cabbage or broccoli, as well as in colorful vegetables and fruits such as corn, oranges, or peaches. It has significant antioxidant properties when taken orally or applied topically.  

According to the manufacturer's claims, Lutein is much more than just a simple antioxidant. It also increases skin hydration and elasticity and absorbs potentially harmful blue light (the one at 400-500 nm also called high energy visible light, aka HEV light). Whether HEV light is bad for the skin or not remains to be seen, but Lutein, being an awesome antioxidant, is a nice addition to any cosmetic product even if HEV-protection turns out to be a fad.
