What does extrinsic aging refer to?

Extrinsic aging refers to the aging process that is influenced by external environmental factors, which are primarily controllable. This includes aspects such as sun exposure, pollution, lifestyle choices like smoking and diet, and other factors that can be managed to some extent. By understanding extrinsic aging, individuals can make informed decisions to protect their skin and minimize the effects of these external factors, thereby maintaining a youthful appearance for longer.

The aspects of aging due to genetics, environmental changes, and intrinsic factors affecting skin elasticity all play roles in the overall aging process, but they do not specifically align with the concept of extrinsic aging as controllable factors. Extrinsic aging is distinct in that it emphasizes the ability to change or influence the effects of aging through lifestyle and environmental modifications.
