1. Epidermis. This outer (superficial) layer of skin, composed of keratinized stratified squamous epithelium, derives from embryonic surface ectoderm. It is avascular, receiving nourishment from vessels in the underlying dermis. Its only innervation (nerve supply) is by unencapsulated (free) nerve endings.
The dermis is the deepest vascular inner skin layer, and is responsible for providing the skin, its strength, and elasticity. This is because of the fibers of the collagen and elastin. The thickness varies, which is 0.3 mm (min) on the eyelids, and 3.0 mm (max) on the back.
