                                                                         Figure 3:  Layers Of The Skin

The original drawing without the descriptive details of the skin's layers as shown here was published by Eli Lilly & Company nearly fifty years ago as drawing pads given to physicians and other health care providers for patient instruction purposes. 

This figure shows the epidermis and dermis together having a total thickness of 4 mm or about 1/8th of an inch, but it actually may range from 2 to 4 mm depending upon the body location.  The epidermis which constitutes the protective or barrier layer of the skin may range from 0.05 to 1.5 mm, the thinnest being the eyelids, and the thickest being the palms and soles.  The outermost layer, the stratum corneum, composed of "dead" cells filled with keratin, is considered by some researchers to be the primary focus of the barrier layer.
