The stratum lucidum, also known as the hyaline layer, is a distinct, clear band of cells found within the epidermis. It is primarily identifiable in the thick, glabrous (hairless) skin found on the palms of the hands and the soles of the feet.12

This layer is easier to distinguish in these specific regions because the epidermis is significantly thicker on these friction surfaces compared to other parts of the body. The stratum lucidum is situated between the stratum granulosum and the stratum corneum, appearing as a clear, translucent zone where the keratinocytes have begun to flatten and lose their nuclei and organelles. Its presence is a characteristic feature of the specialized, high-wear skin found on the palms and soles, which lacks hair follicles.231
