Question: 1 / 400

How do antioxidants affect skin aging?

They promote collagen production

They neutralize free radicals, reducing oxidative stress

Antioxidants play a crucial role in influencing skin aging primarily by neutralizing free radicals. Free radicals are unstable molecules that can damage skin cells, leading to premature aging, fine lines, and wrinkles. By reducing oxidative stress, which is caused by an imbalance between free radicals and antioxidants in the body, antioxidants help protect the skin from this cellular damage.

Oxidative stress is linked to various skin conditions and can accelerate the aging process, making the skin appear older and less healthy. When antioxidants, such as vitamins C and E, are applied topically or consumed through diet, they work to combat these harmful free radicals, thus maintaining skin integrity and promoting a more youthful appearance. This mechanism is fundamental to how antioxidants contribute to overall skin health and aging prevention.
