Where is the stratum lucidum found?

The stratum lucidum is a specific layer of the epidermis that is typically found in areas of thick skin, which require additional protection and resilience. This layer is most commonly located in the palms of the hands and the soles of the feet, where the skin is subject to constant friction and pressure. The stratum lucidum provides an added barrier and aids in the skin's overall durability, contributing to the prevention of damage and the maintenance of moisture in these high-wear areas.

The other locations mentioned—such as the scalp, around the eyes, and in the armpits—do not typically possess the stratum lucidum, as these areas have thinner skin that does not require the same level of protection. The differences in skin structure between these regions underscore the specialized function of the stratum lucidum in accommodating the unique demands placed upon the palms and soles.
