Free radicals can damage the skin when trying to grab an extra electron from other molecules in the body. When these molecules are stolen, it causes direct damage to our skin’s DNA which results in accelerated skin aging.
Similarly one may ask, 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.
In this regard, what role do free radicals play in the aging process?
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.
What vitamins fight free radicals?
Antioxidants — such as vitamins C and E and carotenoids, which include beta-carotene, lycopene and lutein — help protect healthy cells from damage caused by free radicals.

Can free radical damage be reversed?
Your body uses antioxidants to balance free radicals. This keeps them from causing damage to other cells. Antioxidants can protect and reverse some of the damage.
Are free radicals all bad?
Free radicals are compounds that can cause harm if their levels become too high in your body. They’re linked to multiple illnesses, including diabetes, heart disease, and cancer. Your body has its own antioxidant defenses to keep free radicals in check.
How are free radicals harmful to the human body?
If free radicals overwhelm the body’s ability to regulate them, a condition known as oxidative stress ensues. Free radicals thus adversely alter lipids, proteins, and DNA and trigger a number of human diseases. Hence application of external source of antioxidants can assist in coping this oxidative stress.
Does vitamin C serum fight free radicals?
One of the most important benefits of vitamin C is that it fights free radical damage. We are exposed to free radicals through chemicals, pollution and of course UV radiation! Vitamin C is an antioxidant that fights free radical damage to the skin, which can speed along the aging process.
What vitamin C does for your skin?
On top of that, vitamin C is an antioxidant, meaning it protects skin cells from damaging free radicals caused by UV exposure. It also inhibits melanin production in the skin, which helps to lighten hyperpigmentation and brown spots, even out skin tone, and enhance skin radiance.
How antioxidants fight free radicals?
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.
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 is free radical theory and how does it impact aging?
The free radical theory of aging posits that aging is caused by accumulation of damage inflicted by reactive oxygen species (ROS). Although this concept has been very useful in defining the contribution of oxidative damage to the aging process, an increasing number of studies contradict it.
Does ROS cause aging?
One of them is the free radical theory which postulates that reactive oxygen species (ROS), extremely reactive chemical molecules, are the major cause of the aging process. … Toxic effects of ROS on cellular components lead to accumulation of oxidative damage which causes cellular dysfunction with age.
