What causes aging skin?
Short answer: Aging skin is primarily caused by intrinsic factors, such as the natural decline in collagen and elastin production, as well as extrinsic factors, such as sun exposure and lifestyle choices.
Detailed answer
Aging skin is a result of both intrinsic and extrinsic factors. Intrinsic aging is a natural process that occurs as we get older. It involves the gradual decline in collagen and elastin production, which leads to loss of firmness and elasticity in the skin. Additionally, intrinsic factors like genetics can play a role in how our skin ages. Extrinsic factors, on the other hand, are external factors that accelerate the aging process. One of the key extrinsic factors is sun exposure, which damages collagen and elastin fibers and leads to wrinkles, age spots, and uneven skin tone. Other lifestyle choices, such as smoking and poor diet, can also contribute to premature aging of the skin by causing oxidative stress and inflammation. Overall, a combination of intrinsic and extrinsic factors contributes to the aging of the skin.
