What is the action of antioxidants on the skin?

Antioxidants play a vital role in skin health by protecting against free radical damage, which is caused by environmental factors such as UV radiation, pollution, and cigarette smoke. Free radicals are unstable molecules that can damage skin cells, leading to premature aging, inflammation, and various skin conditions. Antioxidants neutralize these free radicals, thereby reducing oxidative stress and the associated harm to the skin.

In addition to protection, antioxidants also aid in the skin's healing processes. This healing can involve reducing inflammation, promoting collagen production, and improving overall skin texture and tone. This multifaceted action helps maintain the skin’s vibrancy and resilience, making antioxidants essential in skincare regimens.

Other options do not reflect the true role of antioxidants. For instance, hydrating the skin is typically attributed to humectants, while promoting sun damage contradicts the protective capability of antioxidants. Additionally, irritation and redness are generally related to irritants or harsh treatments rather than the beneficial elements found in antioxidants.
