In which layer of the skin is eleidin found?

Eleidin is a substance that is specifically found in the stratum lucidum layer of the epidermis. This layer is located just above the stratum granulosum and beneath the stratum corneum. Eleidin is a clear, proteinaceous substance that functions as a transitional form of keratin, providing additional protection and contributing to the overall waterproofing of the skin.

The stratum lucidum is most prominent in areas of thick skin, such as the palms of the hands and the soles of the feet, where it provides an extra layer of resilience against wear and tear. The presence of eleidin in this layer is crucial for forming the skin's barrier function, which helps retain moisture and protect against environmental insults.

Understanding the role of eleidin within the stratum lucidum helps clarify its significance in skin health and biology, making this option accurate in the context of the question regarding its location in the skin.
