How thin is Skin? (human skin)?

The skin is composed of 3 layers: the epidermis, dermis, %26amp; the subcutaneous layer.





Epidermis - outer layer of the skin; provides waterproofing and barrier to infection.





Dermis - middle layer of the skin; located between the epidermis and subcutaneous layer; location for the appendages of the skin.





Subcutaneous Layer - basement membrane; consisting mainly of fat that acts as shock absorber and heat insulator.





If you are pertaining only to the epidermis' thickness, then it is approximately 0.5 to 1 mm.





But if you mean to include the other 2 layers, then, it varies based on the anatomic location, sex and age of individual. Skin is thickest on the palms and soles of the feet. While the thinnest skin is found on the eyelids and in the postauricular region. Male skin is characteristically thicker than female skin. Children have relatively thin skin that progressively thickens until the 4th or 5th decade of life when it begins to thin.
