What are free radicals?

Free radicals are chemically unstable molecules that arise due to various environmental factors, including pollution and UV radiation. They possess unpaired electrons, making them highly reactive and capable of damaging cells, proteins, and DNA. This reactive nature contributes to various health issues, including inflammation, disease, and the aging process of the skin.

In the context of skin health and esthetics, understanding free radicals is crucial because they can significantly impact the skin’s appearance and overall condition. They may lead to premature aging, characterized by fine lines, wrinkles, and loss of elasticity. Therefore, neutralizing free radicals through the use of antioxidants in skincare products is a common approach to maintaining youthful skin and preventing damage.

The other choices describe different concepts that do not accurately reflect what free radicals are or their effects on the body. Organic ingredients that bind water are more about hydration than instability, binding substances pertain to stability within products rather than the reactivity of molecules, and fatty acids related to hydrogen exposure do not capture the essence of free radicals or their implications for health and aging.
