The avascular layer of the skin is the

The epidermis is the avascular layer of the skin, meaning it has no blood vessels of its own. It gets its nutrients and oxygen by diffusion from vessels in the underlying dermis. This outer, protective barrier is made of keratinocytes arranged in several strata and functions without its own vasculature. The layer beneath, the dermis (often called the corium in older terms), is rich in blood vessels, nerves, and connective tissue. The deepest layer, the subcutaneous tissue, contains fat and larger vessels and is also vascular. So, the avascular one is the epidermis.
