The epidermis is the outermost layer of the skin and provides a protective barrier against bacteria, chemicals, and mechanical injuries. It consists of several layers of cells, including the stratum corneum which is the dead outermost layer of skin. The dermis is the layer beneath the epidermis and contains the hair follicles, sweat glands, and blood vessels. The subcutaneous layer is the layer beneath the dermis and contains fat cells. The sebum layer is not a layer of the skin but rather a layer of oil produced by the sebaceous glands in the skin.
