The two functional layers of the skin are the epidermis and the dermis.
- Epidermis: The epidermis is the outermost layer of skin and acts as a protective barrier against the environment. It is composed of several layers of cells, including keratinocytes, which produce keratin, a protein that gives skin its strength and flexibility.
- Dermis: The dermis is the middle layer of skin and contains blood vessels, nerves, hair follicles, and sweat glands. It is responsible for providing the epidermis with nutrients and removing waste products. The dermis also helps to regulate body temperature and provide the skin with its elasticity and strength.
