Free radicals can cause the oxidative stress to skin that results in premature skin aging.Research on rats suggests that free radicals produced in the mitochondria damage the substances that the cell needs to work properly. This damage causes mutations that produce more free radicals, thus accelerating the process of damage to the cell. This theory helps explain aging, since aging accelerates over time.Free radical and aging
[24] The major mechanism of aging attributes to DNA or the accumulation of cellular and functional damage. [25] Reduction of free radicals or decreasing their rate of production may delay aging. Some of the nutritional antioxidants will retard the aging process and prevent disease.

Do free radicals make you age faster?
Research on rats suggests that free radicals produced in the mitochondria damage the substances that the cell needs to work properly. This damage causes mutations that produce more free radicals, thus accelerating the process of damage to the cell. This theory helps explain aging, since aging accelerates over time.

How do free radicals relate to aging?
The free radical theory proposes that ageing is the cumulative result of oxidative damage to the cells and tissues of the body that arises primarily as a result of aerobic metabolism.
Does free radical damage increase with age?
The free radical theory of aging (FRTA) states that organisms age because cells accumulate free radical damage over time. A free radical is any atom or molecule that has a single unpaired electron in an outer shell.

Summary: Diets and beauty products which claim to have anti-oxidant properties are unlikely to prevent aging, according to new research. Scientists in England say this is because a key 50-year-old theory about the causes of aging is wrong.
Can antioxidants help delay the aging process?
While an individual’s genes associated with aging cannot be controlled, many studies suggest that modifications of exercise and nutrition, especially the use of antioxidants, can slow down the aging process.
Do we age because of oxygen?
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.

They are produced either from normal cell metabolisms in situ or from external sources (pollution, cigarette smoke, radiation, medication). When an overload of free radicals cannot gradually be destroyed, their accumulation in the body generates a phenomenon called oxidative stress.

Free radicals are a natural byproduct and can’t be completely eliminated. Free radicals can be formed either naturally in the body through normal metabolic processes or from external factors such as X-rays, cigarette smoking, air pollutants, and industrial chemicals.
What are free radicals in skin?
Free radicals are unstable molecules that damage skin cells. These molecules are missing an electron, so they’re on the hunt. Like a thirsty babe trying to steal your bae, free radicals are looking to steal an electron from stable molecules in order to balance themselves out.

Scientists have long thought that aging could be caused by molecular damage that accumulates in our bodies over the course of time. The damage is an unavoidable by-product of breathing oxygen and other metabolic processes that are necessary to life.
Is aging just oxidation?
Oxidative damage, like other specific damage types viewed in isolation or in combination, does not represent the cause of aging. Instead, biological imperfectness, which leads to inevitable accumulation of damage in the form of mildly deleterious molecular species, may help define the true root of aging.
