Definition
Molecules that neutralize free radicals — unstable molecules caused by UV exposure and pollution — which damage skin cells and accelerate aging.
Every day, UV light and environmental pollution generate free radicals in the skin — unstable molecules that damage collagen, DNA, and cell membranes. Antioxidants (vitamin C, vitamin E, ferulic acid, niacinamide, green tea polyphenols) neutralize those free radicals before they can do harm.
