The stratum lucidum is only found in the palms, fingertips, and soles.
stratum lucidum
The skin is split up into three parts:
The epidermis at the top. This itself is made up of many layers.
Outermost --> Innermost
1) Stratum corneum
2) Stratum lucidum (not always present in thin areas such as the eyelids)
3) stratum granulosum
4) stratum spinosum
5) stratum basale
The epidermis is the thinnest layer of the three and responsible for the barrier properties of the skin. Specifically that is the role of the stratum corneum and the other layers are feeding this layer from below with a constant stream of new cells (dead corneocytes by the time they reach the skin surface)
The layer of skin below the epidermis is the dermis which is filled with nerve endings and hair follicles and a few small blood vessels.
Lastly and the furthest into our bodies we have the and below that we have the subcutis. This is basically just a layer of fat molecules that hold our skin to our bodies.
I hope this helps.

In terms of tissue layers, the skin is composed of two layers, the epidermis and the dermis. It is the dermis that is the thickest layer. The hypodermis is also associated with the skin but is not considered an actual part of the skin. The skin and all its associated hairs, glands, and nerves are called the integumentary system.
No, the soles of the feet and the palms of the hands typically do not have hair follicles.
Skin contains the pigment melanin which is activated by exposure to light. The palms of your hands and the soles of your feet have much thicker layers of skin due to their regular contact and friction with other objects (the ground, tools, etc). Melanocytes exist in the dermal layers of your palms and soles, but are buried beneath the more callous layers and are rarely directed at the sun. You could in theory try to tan your hands but the results would be pretty minimal compared to the rest of your body.
Thick skin found on the palms of the hands and the soles of the feet have no sebaceous glands. The glands are found with hair follicles.

The integumentary system consists of skin, hair, nails, and various glands The integument is made up of two parts: • Cutaneous membrane (skin) • Accessory structures Epidermis consists of stratified squamous epithelium containing several different cell layers - Thick skin: contains 5 layers of cells (keratinocytes) • Found on palms of hands and soles of feet • Thickness of ~ 0.5mm (paper towel) - Thin skin: contains 4 layers of keratinocytes • Covers the rest of the body • Thickness of ~0.08mm
