​What is Dermatology - Name the  three layers of the skin. What makes them up?

 The epidermis, dermis, and subcutis are the three layers of the skin). The epidermis, or outermost layer, is mostly made up of keratinocytes, or epidermal cells. The dermis, which lies beneath the epidermis and is mostly made up of collagen, also contains adnexal structures such as hair follicles, sebaceous glands, apocrine glands, and eccrine glands. The dermis is also home to numerous blood arteries, lymphatics, and nerves. The subcutis, or subcutaneous layer, sits beneath the dermis and is made up of adipose tissue, bigger blood arteries, and nerves. The base of hair follicles and sweat glands may also be found in the subcutis
