The free radical theory of aging asserts that many of the changes that occur as our bodies age are caused by free radicals. Damage to DNA, protein cross-linking and other changes have been attributed to free radicals. Over time, this damage accumulates and causes us to experience aging.
Herein, how do free radicals affect skin?
Free radicals are responsible for breaking down our skin’s collagen, resulting in unflattering skin blemishes like wrinkling, dark spots, fine lines and loose, saggy skin.
Accordingly, what removes free radicals from the body?
Antioxidants neutralize free radicals by giving up some of their own electrons. In making this sacrifice, they act as a natural “off” switch for the free radicals. This helps break a chain reaction that can affect other molecules in the cell and other cells in the body.
Do antioxidants slow aging?
“A healthy, balanced diet is very important for reducing the risk of developing many diseases associated with old age, such as cancer, diabetes and osteoporosis,” he says. “But there is no clear evidence that dietary antioxidants can slow or prevent aging.
How does oxidation cause aging?
Oxidative stress causes cells and entire organisms to age. If reactive oxygen species accumulate, this causes damage to the DNA as well as changes in the protein molecules and lipids in the cell. The cell ultimately loses its functionality and dies. Over time, the tissue suffers and the body ages.

What causes free radicals?
Free radicals are highly reactive and unstable molecules that are produced in the body naturally as a byproduct of metabolism (oxidation), or by exposure to toxins in the environment such as tobacco smoke and ultraviolet light.
What is free radicals in body?
Free radicals are oxygen-containing molecules with an uneven number of electrons. The uneven number allows them to easily react with other molecules. Free radicals can cause large chain chemical reactions in your body because they react so easily with other molecules. These reactions are called oxidation.
