The skin is composed of two layers: the epidermis and the dermis. Underneath these layers lies the hypodermis. The epidermis is stratified squamous epithelium. The dermis is composed of a papillary layer and a reticular layer. The reticular layer of the dermis is made up of dense irregular connective tissue.
There is 1 layer of skin, but the skin itself is made up of 7 different layers on a microscopic level. Each layer has a different function. We normally only talk about the 3 main layers within the skin-the epidermis, the dermis, and the subcutaneous tissue.
