What factors contribute to skin aging that individuals have little control over?

Intrinsic factors are biological and genetic elements that contribute to the aging process of the skin, and individuals generally have little control over these factors. These include genetics, hormonal changes, and the natural aging process itself, which can affect skin elasticity, moisture retention, and overall appearance. As people age, their skin undergoes natural changes such as reduced collagen production and slower cell turnover, leading to wrinkles, sagging, and a dull complexion.

In contrast, extrinsic factors such as sun exposure, pollution, and lifestyle choices (like smoking and diet) are external influences that individuals can actively manage to mitigate skin aging. Environmental factors similarly relate to those external influences impacting skin health. Behavioral factors cover habits and activities that individuals can modify, such as skincare routines and sun protection habits. Therefore, intrinsic factors are specifically relevant to aging that is largely predetermined and not influenced by personal lifestyle choices.
