How do antioxidants benefit the skin?

Antioxidants play a crucial role in skin health primarily by protecting against free radical damage. Free radicals are unstable molecules that can harm skin cells, leading to premature aging, inflammation, and various skin conditions. By neutralizing these free radicals, antioxidants help to prevent oxidative stress that can cause cellular damage. They contribute to maintaining skin’s firmness, elasticity, and overall appearance.

Additionally, antioxidants can enhance the skin's natural barrier function, help reduce inflammation, and promote a more radiant complexion. Products rich in antioxidants, such as vitamins C and E, can be highly beneficial in skincare regimens aimed at combating environmental stressors like pollution and UV radiation.

The other options do not accurately represent the benefits of antioxidants. Increasing oil production, promoting collagen breakdown, and causing skin irritation are not functions of antioxidants and could lead to adverse effects on skin health. Overall, the protective capacity of antioxidants against free radical damage is fundamental for youthful, healthy skin.
