What is the importance of collagen in the skin?

Collagen plays a vital role in maintaining the structure and integrity of the skin. It is a key protein that forms a fibrous network, providing strength and support. This protein contributes to the skin's elasticity, allowing it to stretch and bounce back after being pulled or compressed. As we age, collagen production decreases, leading to sagging skin and wrinkles, demonstrating its importance in preserving youthful skin appearance. While moisture, sensory functions, and blood flow are also important aspects of skin health, they are not direct functions of collagen itself.
