When free radicals overpower our body and trigger oxidative stress, it can impact the different layers of the skin.
Another reason why daily sunscreen use is absolutely crucial. How does sunlight cause free radicals in your body? Too much UV radiation from the sun can overwhelm your system, provoking these unstable molecules and triggering oxidative stress - AKA the process of photoaging. But when the antioxidant-producing capacity becomes overwhelmed by the number of free radicals, damage can occur as our body can’t keep up. Normally, our body can fight off this stress through its own antioxidant defenses. Oxidation consists of chemical reactions that damage our cells. What do free radicals do to the body?Īn overload of free radicals sets off a process called oxidative stress. But many times, they’re introduced from an outside source, like tobacco smoke, toxins, pollutants, and especially sun exposure. Our body can produce free radicals through natural biological processes. Free radicals damage cell proteins and DNA by altering their chemical structure. These molecules can trigger a long chain of chemical reactions in the body called oxidation, causing harm and signs of aging.
That single electron allows them to interact freely with other molecules, which isn’t always a good thing. What makes them so unstable? They’re oxygen-containing molecules that have an unpaired electron. Free radicals are unstable atoms that can damage the cells in the body.
