What role do antioxidants play in skincare?

Antioxidants play a crucial role in skincare primarily by neutralizing free radicals. Free radicals are unstable molecules that can cause oxidative stress, leading to premature aging, inflammation, and other skin issues. By neutralizing these free radicals, antioxidants help prevent cellular damage, promote skin health, and maintain a youthful appearance.

In addition to this primary function, while some antioxidants might indirectly help with hydration or skin coloration through their overall skin health benefits, their defining role remains focused on combating free radicals. The process of enhancing skin color does not accurately describe the primary action of antioxidants, nor does increasing sebum production align with their function, as antioxidants are not involved in oil production. Overall, their protective quality against oxidative damage is what makes them a vital component in many skincare formulations.
