What is a common change in older skin that contributes to the formation of wrinkles?

1. Increased collagen production

2. Thinning of the skin

3. Enhanced sebaceous gland activity

4. Increased dermal papillae volume

The correct answer is: Thinning of the skin

Thinning of the skin is a common change that occurs with aging and significantly contributes to the formation of wrinkles. As individuals age, the skin undergoes various structural changes, including a reduction in the thickness of the epidermis and dermis. This reduction is attributed to several factors, including decreased production of collagen and elastin, which are essential for maintaining skin elasticity and firmness. As the skin becomes thinner, it is less able to withstand environmental damage and loses its youthful appearance, leading to the development of fine lines and wrinkles. Other factors associated with aging, such as decreased moisture retention and reduced sebaceous gland activity, also play a role in the overall appearance of the skin; however, it is primarily the thinning of the skin that has a direct and pronounced impact on wrinkle formation. Enhanced sebaceous gland activity would typically lead to oilier skin, which is not characteristic of aging skin, and increased dermal papillae volume is not commonly seen in older skin.
