What is the outer layer of the skin?

Explanation:
The outermost layer of the skin is the epidermis. It acts as the protective barrier, keeping microbes out and reducing water loss. It is avascular, meaning it doesn’t have blood vessels, and relies on nutrients from the underlying dermis. The epidermis is renewed from cells produced in its deepest layer and gradually move outward, forming the tough, protective surface. Beneath it lies the dermis, with blood vessels and nerves, and deeper still is the subcutaneous (hypodermis) layer of fat and connective tissue.
