What is the primary purpose of collagen in the skin?

The primary purpose of collagen in the skin is to give structure and support. Collagen is a vital protein that forms a significant part of the skin's structure, providing it with strength, elasticity, and firmness. As the most abundant protein in the body, collagen maintains the skin's integrity and plays a crucial role in its overall appearance and feel.

While moisture retention and healing are important aspects of skin health, they are not the primary function of collagen. Moisturizers and other skincare ingredients usually address hydration directly, while growth factors and other components facilitate healing. Therefore, the role of collagen is more aligned with providing a foundational framework that sustains the skin's physical properties, making it essential for maintaining a youthful and resilient appearance.
