Layers of the Skin
LAYERS OF THE SKIN
Epidermis
This is the outer avascular layer of the skin that is made up of epithelial cells. It regenerates every 2-4 weeks, subject to an individual's age and friction forces applied to the skin. All the nutrients are supplied from the dermis below it.
Dermis
This is the middle layer of the skin. It is a very vascular layer containing nerves, connective tissue, collagen, elastin and specialized cells such as fibroblasts and mast cells. It is a very important level responsible for the inflammatory processes which occur in response to trauma and infection.
Hypodermis
Skin Appendages include hair, nails, sebaceous glands and sweat glands

Hypodermis
The innermost layer is commonly known as the subcutaneous layer. It has a supportive role to the superficial layers. It is made up of adipose tissue, connective tissue and blood vessels.
It also has a very important role in storing fats, protecting organs and temperature regulation.
