Antioxidants play a crucial role in skincare primarily because they protect the skin from free radicals and environmental damage. Free radicals are unstable molecules that can cause oxidative stress, leading to premature aging and various skin issues. Antioxidants neutralize these free radicals by donating an electron, which stabilizes them and prevents them from causing harm to skin cells.

Moreover, antioxidants help mitigate the effects of environmental aggressors like UV radiation and pollution, which can contribute to skin damage and lead to conditions such as inflammation and hyperpigmentation. By incorporating antioxidants into skincare regimens, individuals can enhance the overall health and appearance of their skin, making it look more youthful and vibrant.

Other options relate to different aspects of skincare but do not address the primary role of antioxidants. For instance, some may refer to the benefits of increasing blood circulation, moisturizing, or balancing skin pH, which are important in skincare but distinct from the protective functions that antioxidants serve.
