What happens to the skin with aging?

As the skin ages, one of the significant changes that occurs is a decrease in collagen production. Collagen is a key protein that provides structure, strength, and elasticity to the skin. With aging, the body’s ability to produce collagen diminishes, leading to a loss of firmness and an increase in the appearance of fine lines and wrinkles. This natural decline affects the skin’s overall integrity, resulting in sagging and a rough texture, which are characteristic of aged skin. Consequently, this decreased collagen significantly contributes to the visible signs of aging.

In contrast, the other options do not accurately depict the aging process. For example, elastic fibers actually decrease rather than increase, affecting the skin's elasticity negatively. Similarly, improved temperature control is not commonly associated with aging; older adults may experience more difficulties in temperature regulation. Increased sebaceous activity can vary, but it generally does not characterize the typical aging process, as many experience reduced oil production leading to drier skin.
