Astaxanthin is a red carotenoid (from algae and the animals that eat it) and a particularly potent antioxidant that, unusually, spans cell membranes.
Its most promising human evidence is for skin, modest improvements in elasticity and UV resilience, with more tentative signals for exercise recovery, eye and cardiovascular markers. It is fat-soluble (take with a meal) and well tolerated; effects are real but modest.
