Question

Quizplus · Accepted Answer

Macrophages are immune cells that play a critical role in defending the body against infections and diseases. As we age, the number of macrophages in the skin decreases, and the ones that are present become less efficient in their functioning. This leads to a decreased ability of the aging skin to fight off infections and diseases. Collagens are proteins that provide structural support to the skin, melanocytes produce melanin that gives color to the skin, and sebaceous glands produce oil to moisturize the skin - while these play important roles in skin health, they are not directly related to the skin's immune system.
