Antioxidants play a crucial role in skincare primarily by neutralizing free radicals and protecting against oxidative stress. Free radicals are unstable molecules that can cause cellular damage, which is often linked to premature aging and various skin conditions. By targeting these free radicals, antioxidants help to mitigate their harmful effects, promoting a healthier complexion and reducing the signs of aging.

Oxidative stress is caused by an imbalance between free radicals and antioxidants in the body. With increased exposure to environmental factors like UV radiation, pollution, and even stress, the production of free radicals can surge, leading to damage in skin cells. Antioxidants, such as vitamins C and E, green tea extract, and coenzyme Q10, work to counteract this damage, enhancing skin repair mechanisms and maintaining overall skin health.

While sun protection and creating barriers against pollutants are important aspects of a complete skincare routine, they do not encapsulate the primary role of antioxidants. Instead, antioxidants serve as a fundamental defense mechanism against the internal and external damage that contributes to skin problems.
