What is the Role of the Extracellular Matrix in the Dermis?
The extracellular matrix (ECM) in the dermis is a complex network of macromolecules, including collagen, elastin, and proteoglycans. Collagen fibers provide tensile strength, while elastin fibers allow the skin to return to its original shape after stretching or contracting. Proteoglycans and glycosaminoglycans, such as hyaluronic acid, contribute to the skin's hydration and viscoelastic properties.
