* Collagen: The most abundant protein in the dermis, collagen provides structure and strength, giving the skin its elasticity and firmness.
* Elastin: Another important protein, elastin provides the skin's ability to stretch and recoil, allowing it to return to its original shape after being stretched or compressed.
* Keratin: While primarily associated with the epidermis, keratin also plays a role in the dermis, particularly in the hair follicles and sweat glands. It contributes to the strength and resilience of these structures.
* Fibronectin: This protein helps bind collagen and elastin fibers together, contributing to the dermis's overall structural integrity.
* Laminin: Found in the basement membrane, a thin layer separating the dermis from the epidermis, laminin helps anchor the epidermis to the dermis.
These proteins, along with other components, contribute to the dermis's vital functions of providing support, elasticity, hydration, and protection for the skin.
