The next big skincare ingredient? Astaxanthin. The powerful antioxidant, derived from a microalgae, has been used for everything from aiding muscle recovery to treating autoimmune diseases, so it was only a matter of time before it hit the beauty industry. Claimed to be up to 1,000 times more effective at fighting free radicals than vitamin E, it’s now in a vitamin supplement called Astavita Skin Defense Complex, a pill designed to improve skin from the inside out (astavita.com). And 3 Lab included it in its new Perfect “Glow” Complex serum: The company found that aside from Astaxanthin’s antioxidant properties, it also enhances skin elasticity and helps reduce melanin deposits, which can lead to age spots. $95; at Barneys New York.
