What explains the complaint of thin and dry skin in an older woman?

1. Genetic predisposition

2. Loss of subcutaneous fat and lower collagen content

3. Damage from aging alone

4. Environmental factors such as sun exposure

The correct answer is: Loss of subcutaneous fat and lower collagen content

The complaint of thin and dry skin in an older woman can be well explained by the loss of subcutaneous fat and lower collagen content that occurs with aging. As individuals age, their skin undergoes structural changes, primarily due to a decrease in the amount of collagen and elastin fibers within the dermis. These proteins are essential for maintaining skin's firmness and elasticity. Additionally, there is often a reduction in subcutaneous fat, which normally provides insulation and cushioning to the skin. This combination of reduced structural support and cushioning leads to skin that appears thinner, feels drier, and is more prone to wrinkles and other signs of aging. While genetic predisposition, environmental factors, and natural aging processes all have roles in skin health, the specific combination of decreased fat and collagen is the primary cause of the symptom described, making it the most comprehensive explanation for the complaint of thin and dry skin in this context.
