What skincare issue is associated with chronic smoking?

Chronic smoking is closely linked to extrinsic aging of the skin. This form of aging is primarily influenced by environmental factors rather than internal biological processes. In the case of smoking, the active ingredients in tobacco smoke, along with the act of smoking itself, contribute to the breakdown of collagen and elastin — essential proteins that maintain skin elasticity and firmness. Due to these changes, smokers often experience premature wrinkles, sagging skin, and a dull complexion, which are hallmarks of extrinsic aging.

Additionally, smoking restricts blood flow, reducing oxygen and nutrient delivery to the skin, further exacerbating aging signs. The exposure to harmful chemicals in smoke also leads to oxidative stress, which can damage skin cells and accelerate aging. This comprehensive understanding highlights the detrimental effects of smoking on skin health and the aging process, justifying why extrinsic aging is the correct choice in relation to chronic smoking.
