Oxidative aging

Oxidative aging is the process where exposure to oxygen causes gradual changes in a material's structure, often leading to deterioration. In biological systems, it involves the formation of harmful molecules called free radicals that damage cells, contributing to skin wrinkles, loss of elasticity, and other age-related effects. In materials like metals or rubber, oxidation can cause corrosion or cracking over time. Overall, oxidative aging results from reactions between oxygen and the substance's components, gradually weakening or altering its original properties and appearance.
