One of the layers of the epidermis situated just beneath the stratum corneum and present only in the thick skin of the palms of the hands and the soles of the feet. Also called the transparent layer.

The layer of the epidermis just beneath the stratum corneum, consisting of two or three layers of flat clear cells with atrophied nuclei. Also called stratum lucidum.

For other uses, see Stratum lucidum (disambiguation).

The stratum lucidum is a layer of the epidermis found throughout the body, but is thickest on the palms of the hands and the soles of the feet. Located between the stratum granulosum and stratum corneum layers. It is composed of three to five layers of dead, flattened keratinocytes. ^[1][2] The thickness of the lucidum is controled by the rate of mitosis of the epidermal cells. In addition, melanocytes determine the darkness of the stratum lucidum.
