How can advanced age impact tissue integrity?

As individuals age, several physiological changes occur that affect tissue integrity, particularly in the skin. One of the most significant changes is that aging skin becomes thinner due to a decrease in collagen and elastin production. These proteins are essential for maintaining the skin's structure, strength, and elasticity. Consequently, aging skin is more fragile and has a reduced ability to withstand mechanical stress or injury.

Additionally, the reduction in fatty tissue in the subcutaneous layer makes the skin less cushioned, increasing the risk of trauma and pressure injuries. Along with thinning, the skin's ability to heal also declines with age, leading to prolonged recovery from wounds and an increased likelihood of complications such as infections.

Understanding these changes is crucial for effectively managing and protecting the skin of older adults, as they are at a higher risk for skin-related issues.
