Approximately what percent of the dermis is made of collagen?

The dermis is primarily composed of collagen, which is a key structural protein that provides strength and elasticity to the skin. Approximately 70% of the dermis is made up of collagen. This robust network of collagen fibers is crucial for maintaining the skin's firmness and structure, allowing it to withstand various forms of stress and tension.

Collagen serves as a foundational element in the extracellular matrix of the skin, helping to support the overlying epidermis and house various other components like blood vessels, nerves, and connective tissues. This significant percentage indicates the importance of collagen in the overall health and appearance of the skin. The remaining composition of the dermis includes elastin, reticular fibers, ground substance, and various cells, which all play complementary roles but are significantly less abundant than collagen itself.
