The main component of the skin is the epidermis. The epidermis is the outermost layer of skin and is responsible for protecting the body from the environment. It contains cells that produce keratin, a protein that waterproofs and strengthens the skin. The epidermis also has cells with melanin, the dark pigment that gives skin its color and helps protect it from the sun's harmful rays.
The skin also has two other main layers: the dermis and the subcutis. The dermis is located beneath the epidermis and contains blood vessels, nerves, and hair follicles. The subcutis is the deepest layer of skin and is made up of fat and connective tissue.
