What is the primary function of collagen in the skin?

Collagen plays a crucial role in maintaining the structure and elasticity of the skin. As a primary protein found in connective tissues, collagen provides the skin with strength and firmness, allowing it to maintain its shape and resilience. Over time, the natural production of collagen diminishes, which can lead to sagging and wrinkles, making its role in skin health even more significant.

While hydration is important for skin health, it is typically associated with other substances such as hyaluronic acid, which attracts and retains water in the skin. Pigmentation is largely determined by melanin production, and barrier functions of the skin are primarily attributed to lipids and other protective proteins, which help shield the skin from environmental pollutants and pathogens. Each of these functions is important for overall skin health, but they do not fulfill the structural role that collagen does.
