Free radicals are unstable chemical molecules produced in small quantities in the body. They are primarily synthesized in cells
during oxygenating reactions. Their chemical instability makes them extremely reactive molecules, some reactions with cells leading to cellular damage. Large numbers of free radicals can, therefore, have a visible effect on skin ageing, and could be involved in numerous conditions, such as cancer
, heart disease, neurogenerative disorders like Alzheimer's disease
, or prescribed drug intoxication.
