β-Carotene is known to have antioxidant activity, the ability to scavenge free radicals and reduce oxidative stress that occurs in the body. However, researchers have paid a little attention to the potential of β-Carotene as an anti-aging agent. The aim of this study was to describe the potential of β-Carotene from natural sources as anti-aging agent via antioxidant mechanism. Literature study was conducted on 28 publications associated with natural sources of β-Carotene, mechanism of anti-aging and antioxidant in the body. The results showed that the best antioxidant activity of β-carotene in scavenging free radicals was at low concentrations while taking into account antioxidant activity, dose, and half-life. UV exposure and air pollution can be a source of free radicals that cause aging of the skin. High antioxidant activity of β-carotene has the potential as anti-aging agent in the form of a beauty serum to treat premature aging of the skin.
