The epidermis is the outer (epi in Greek meaning over or upon) of the two layers that make up the skin (or cutis), the inner layer being the dermis.
There are five distinct sub-layers of the Epidermis: 1  Stratum corneum: the outermost layer, made of 25-30 layers of dead flat keratinocytes. Lamellar granules provide water repellent action and are continuously shed & replaced. 2  Stratum lucidum: Only found in the fingertips, palms of hands, & soles of feet.
