Understanding the Layers of Skin: Epidermis, Dermis & Hypodermis

The layers of the skin, from the outermost to the innermost, are:

1. Epidermis: This is the outermost layer of the skin and it protects the body from the elements. It is made up of multiple layers of cells, including keratinocytes, melanocytes, and Langerhans cells.

2. Dermis: This is the middle layer of the skin and it provides support and elasticity. It is made up of connective tissue, blood vessels, hair follicles, and glands.

3. Hypodermis (Subcutaneous Layer): This is the innermost layer of the skin and it provides insulation and protection. It is made up of fat cells, connective tissue, and blood vessels.
