Lucidum
The stratum lucidum, which is present in the thick skin of the palms and soles, is absent in thin skin
In thin skin, the epidermis lacks a stratum lucidum layer found in thick skin. Additionally, thin skin has fewer layers of the stratum corneum, which is the outermost layer of the epidermis. Overall, thin skin is more flexible and sensitive compared to thick skin.

The Stratum Lucidum
Your skin as the patriotic colors, let's salute the red, white, and blue
Stratum lucidum (in thick skin) is a well defined epidermal layer found under the corneum region of the skin of the palms and soles. Main function of this stratum is to help the skin handle friction and also waterproof it. It is a thin transitional layer of epidermis found between the 'horny' and 'granular' layers.
The stratum lucidum.
Stratum lucidum
Thick skin ( contains five layers: startum basala, spinosum, granulosum, lucidum and corneum)It has prominent stratum corneum and well- developed stratum granulosum. In addition ,it has additional epidermal layer which is named as stratum lucidum. On the top of this ,thick layer lacks integumentary appendages: hair follicles, sebaceous glands and arrector pili muscles. Generally, thick skin is located to those aeas subjected to wear and tear and mainly on the palms of the hand and soles of the feet. Thin skin ( contains only four layers: startum basala, spinosum, granulosum, and corneum)It has less prominent stratum corneum than thick skin and less developed stratum granulosum. But, it is without clear epidermal layer, stratum lucidum. Unlike the thick skin, thin skin has hair follicles, sebaceous glands and arrector pili muscles . Such type of skin is dominant and lines most of the body surface. stratum lucidum
stratum lucidum
stratum corneum in thin skin and stratum lucidum in the thick skin
The skin on the palm of the hand and sole of the feet is called thick skin. It has an additional layer called the stratum lucidum, which is not present in thin skin. This layer of skin helps to provide extra protection against wear and tear in areas that experience a lot of friction and pressure.
