What is intrinsic disease?

What is an example of extrinsic aging?
Extrinsic ageing of skin is a distinctive declination process caused by external factors, which include ultra-violet radiation, cigarette smoking, air pollution , among others. Of all extrinsic causes, radiation from sunlight has the most widespread documentation of its negative effects on the skin.
How does chronic inflammation affect intrinsic aging?
