Beta-Carotene
Explained
Beta-Carotene is a fat-soluble carotenoid pigment. It is the thing responsible for giving carrots, sweet potatoes, apricots, and other orange-yellow produce their color.
It is a potent antioxidant that neutralizes free radicals (mainly reactive oxygen species) that come at your skin from both the environment and internal processes.
When applied topically, beta-carotene accumulates in your outermost layer of skin and acts as a first-line defense against photo-oxidative stress.
Research has established that carotenoids like beta-carotene boosts your skin's innate resistance against UVB induced erythema. Please know this does not mean beta-carotene can replace your sunscreen.
Newer studies show it can also help inhibit molecular markers of oxidative stress like MMP-1 and MMP-9, enzymes that break down collagen.
In some cases, it can be used as a cosmetic colorant as well (INCI name: CI 40800).
Beta-carotene pairs well with other antioxidants like Vitamin E and Vitamin C for a synergistic effect.
