Skin consists of three main layers: epidermis, dermis and hypodermis. What type of tissue makes up this layer? The hypodermis (also called the subcutaneous layer or superficial fascia) is a layer directly below the dermis and serves to connect the skin to the underlying fascia (fibrous tissue) of the bones and muscles. Beginning on the surface of the skin in the region of the thigh, list, in order, the layers of the tissue the The facial skin begins to droop and sag; the bones and muscles of the face also lose volume. The 40X image shows: e = epidermis d = dermis h = hypodermis sw Keratinocytes are the most common type of cell in the epidermis and are responsible for the synthesis of the protein keratin. The epidermis , composed of the outermost layers of skin, consists of four layers in most areas of the body and five layers on areas of the body that have thick skin, such as the soles of the feet. The epidermis is the outermost layer, providing the initial barrier to the external environment. The layers of the skin include the epidermis (the outermost layer), the dermis (the next layer which is loaded with blood vessels and nerves), and then the hypodermis.1 p = papillary layer of dermis.

The skin consists of two layers, the epidermis and the dermis. (The hypodermis or subcutaneous layer is not part of the skin [citation needed].)
