Main Epidermal Layers
The two main epidermal layers are the stratum basal and the stratum corneum.
Stratum Basale is the basement layer where the cells are nourished by the blood vessels found in the dermis. Here the cells grow and divide through the process of mitosis. the new cells are then pushed away from the stratum basal towards the surface of the skin. Specialized called here known has melanocytes, produce melanin. melanin absorbs UV radiation and prevents DNA mutation and other damaging effects. Melanocytes produce melanin, which give skin its color. the amount of melanin in someone's skin causes the differences in skin colors.

The stratum corneum includes many tough layers of tightly packed dead cells which build up in the outermost epidermis. Keratinization, which is when the cytoplasm fills with tough, fibrous, waterproof keratin protein, and causes cells to harden. These dead cells are eventually shed.
