As people age, what tends to happen to their skin?

As people age, their skin tends to become drier and more wrinkled due to several physiological changes. The production of natural oils decreases, leading to a loss of moisture and making the skin less able to retain hydration. Additionally, the outer layer of skin, known as the epidermis, thins over time, contributing to increased visibility of fine lines and wrinkles. The underlying layer of fat that provides cushioning also diminishes, resulting in sagging and a less plump appearance.

Furthermore, the collagen and elastin fibers in the skin, which are responsible for its elasticity and strength, break down with age. This change promotes the formation of wrinkles and a less taut appearance. The overall combination of these factors makes skin more susceptible to damage, dryness, and a decrease in resiliency. Therefore, the correct answer highlights the common experience of skin aging, which includes increased dryness and wrinkle formation.
