What is the role of collagen in aging skin?

• A. It prevents skin from drying out
• B. It provides structure and firmness to the skin
• C. It absorbs UV radiation
• D. It promotes skin cell turnover

Answer: (B)

Collagen is a crucial protein in the skin that contributes significantly to its structure and firmness. As a structural protein, collagen forms a network of fibers that provide support and elasticity to the skin. This is particularly important for maintaining the skin's youthful appearance. With aging, the production of collagen decreases, leading to a loss of firmness, causing the skin to sag and develop wrinkles. Therefore, the presence of collagen is directly linked to the skin's ability to remain taut and well-structured. Its role as a foundational element in the extracellular matrix is essential for maintaining the overall integrity and resilience of the skin. While collagen does not prevent skin from drying out, absorb UV radiation, or directly promote skin cell turnover, it does lay the groundwork that allows the skin to function effectively and maintain its health, which indirectly supports these other vital aspects of skin physiology.
