Final answer:
Skin resiliency refers to the skin's ability to regain its shape after stretching, which diminishes with aging due to changes in the integumentary system affecting the dermis and epidermis.
Step-by-step explanation:
An evaluation of skin resiliency is an assessment of the skin's elasticity and its ability to return to its original shape after being stretched or compressed. As a person ages, changes occur in the integumentary system, leading to decreased cell division, reduced metabolic activity, and diminished blood circulation, hormonal levels, and muscle strength. These alterations can be witnessed in the skin's epidermis becoming thinner due to reduced mitosis, and the dermis, which provides skin elasticity, showing a slowed ability to regenerate. This contributes to slower wound healing and the sagging of skin, indicating that resiliency evaluation might serve as a good indicator of overall skin health and aging.
