What role does collagen play in the skin?

Collagen plays a crucial role in supporting the skin's structure. It is a major protein found in the dermis, the middle layer of the skin, and acts as a scaffold that gives the skin its strength, firmness, and overall structural integrity. This protein helps to maintain the skin's elasticity and resilience, making it less prone to sagging and wrinkling as we age, but its primary function is to provide foundational support.

While aspects like moisture retention and oil regulation may be influenced by other factors in the skin, such as hyaluronic acid and sebaceous glands, respectively, collagen specifically is known for its structural contributions. Understanding the importance of collagen helps in comprehending various skin care treatments and the natural aging process, emphasizing why it is often a key focus in cosmetic procedures and products aimed at improving skin health and appearance.
