What type of aging is primarily caused by environmental factors such as sun exposure, alcohol consumption, and smoking?

The correct answer focuses on extrinsic aging, which refers to the aging process primarily influenced by external factors. This type of aging is significantly impacted by environmental elements, including sun exposure, which can lead to photoaging, and lifestyle choices such as smoking, which damages the skin and accelerates the formation of wrinkles. Alcohol consumption also adversely affects skin health by dehydrating the skin and impairing its natural repair processes.

Extrinsic aging contrasts with intrinsic aging, which is genetically determined and refers to the natural aging process that occurs over time, influenced by factors like genetics and biological processes. Biological and organic do not specifically refer to environmental impacts but rather to overall health or structural components of living organisms. Understanding extrinsic aging is vital for estheticians, as it emphasizes the importance of protective measures, such as sunscreen use and a healthy lifestyle, in maintaining skin health and appearance.
