What role does collagen play in the skin?

Collagen is a crucial protein in the skin that provides structure and elasticity. It forms a dense network within the dermis, which helps support the skin's shape and resilience. This structural role is vital, as collagen contributes to the skin's firmness and ability to resist sagging and wrinkles. As we age, collagen production naturally decreases, leading to a loss of support that can result in noticeable changes in skin texture and elasticity.

While pigmentation, blood circulation, and hydration are important to overall skin health, they are not direct functions of collagen. Pigmentation is mainly influenced by melanin, blood circulation is regulated by the vascular system, and skin hydration primarily involves water content and the role of moisturizing agents. Therefore, the focus on collagen as a provider of structure and elasticity in the skin is fundamental to understanding how skin remains youthful and robust.
