Flexi Says: The epidermis is the outermost layer of the skin. It forms the waterproof, protective wrap over the body's surface. Although the top layer of the epidermis is only about as thick as a sheet of paper, it is made up of 25 to 30 layers of cells. The epidermis also contains cells that produce melanin. Melanin is the brownish pigment that gives skin and hair their color. Melanin-producing cells are found in the bottom layer of the epidermis. The dermis is the layer of skin directly under the epidermis. It is made of tough connective tissue. The dermis contains hair follicles, sweat glands, oil glands, and blood vessels. It also holds many nerve endings that give you your sense of touch, pressure, heat, and pain.
