Intrinsic aging is primarily affected by which factor?

Intrinsic aging is primarily characterized by the natural aging processes that occur within the body, which are influenced by genetic factors and the natural decline of cellular functions over time. Cellular recession refers to the gradual decline in the number and function of cells within the body as one ages, leading to slower regeneration and repair processes. This includes factors like reduced collagen and elastin production, which are crucial for maintaining skin elasticity and firmness.

While external factors such as sun exposure, nerve stimulation, and pollution can contribute to the visible signs of aging, intrinsic aging is predominantly driven by internal biological processes. Therefore, understanding intrinsic aging involves recognizing the role of cellular changes that occur naturally over time. This focus on cellular recession highlights the importance of genetic predispositions and the natural aging rate of different tissues in the body, particularly in the skin.
