What are common changes in the integumentary system as a person ages?

As a person ages, the integumentary system, which includes the skin, hair, and nails, undergoes several noticeable changes. Dry skin is common due to decreased oil production, which often results in a lack of moisture and increased vulnerability to irritation. Wrinkling occurs as the skin loses elasticity and collagen, factors that provide firmness and resilience; this is a natural consequence of aging skin that reflects prolonged exposure to environmental factors and the natural reduction of skin cell turnover. Additionally, graying hair results from a decrease in melanin production, leading to the loss of color in hair follicles.

These changes are all directly associated with the aging process and highlight the decline in the skin's ability to retain moisture and maintain structural integrity. Understanding these aspects is essential for recognizing how aging affects the integumentary system and its overall impact on a person's appearance and comfort.
