The Dermis
The Dermis — the thick middle layer of skin beneath the epidermis, providing structural strength, elasticity, and nourishment. It is rich in collagen and elastin fibers produced by fibroblasts, and it houses blood vessels, nerves, hair follicles, and sweat and oil glands. This layer gives skin much of its firmness and resilience.
Key points
- The dermis lies between the epidermis and the hypodermis and is far thicker than the epidermis in most areas.
- It contains collagen and elastin fibers within a hydrating matrix that give skin its strength and flexibility.
- Fibroblasts are the main cells of the dermis, producing collagen, elastin, and other components of the extracellular matrix.
- The dermis houses blood vessels, nerve endings, hair follicles, sebaceous glands, and sweat glands.
