Tinea Faciei Anatomy

To better understand tinea faciei, it helps to understand the anatomy of the skin.

The skin contains three main layers:

  • Epidermis:
    • The superficial layer that makes up the surface of the skin
    • It is composed of skin cells and can be divided into 5 layers based on cell type.
    • The top layer of the epidermis, the stratum corneum, is made of dead, flat skin cells that shed about every 2 weeks.
    • The thickness of the epidermis varies, according to location: it is very thick over the soles of the feet, and very thin over the ears.
  • Dermis:
    • Lies beneath the epidermis
    • Also varies in thickness depending on the location of the skin. It is .3 mm on the eyelid and 3.0 mm on the back.
    • The dermis is composed of 2 layers that contain a connective tissue called collagen
    • The dermis contains blood vessels, nerves, sweat glands, and hair follicles.
    • The number of structures in the dermis varies, according to location.
    • The dermis under the arms contains more sweat glands and hair follicles than the dermis on the back.
  • Subcutaneous layer:
    • Mainly fat and connective tissue.
    • Contains blood vessels and nerves.
