Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue and
Stratum Basale (bottom layer). Sits directly on top of the dermis. This layer furnishes cells to replace those lost in the upper layers of the epidermis. Melanin is formed here to protect against ultraviolet radiation.
