Antioxidants play a crucial role in skincare primarily due to their ability to protect the skin from damage caused by free radicals. Free radicals are unstable molecules that can result from environmental stressors such as UV radiation, pollution, and even stress. They can lead to oxidative stress, which can damage skin cells and accelerate the aging process. Antioxidants neutralize these free radicals, thereby reducing their harmful effects and helping to maintain the overall health and appearance of the skin.

By providing this protective mechanism, antioxidants not only help to prevent premature aging but also contribute to the skin's resilience against various environmental aggressors. This protective function is a foundational aspect of many skincare regimens, showcasing why this role is emphasized in the context of skin health.
