Which layer of the epidermis is a clear, transparent layer located under the stratum corneum?

• A. Stratum lucidum
• B. Stratum corneum
• C. Dermatology
• D. Trichology

Answer: (A)

The epidermis has several stacked layers, with the outermost being the stratum corneum. Directly beneath that in thick skin is a thin, clear layer called the stratum lucidum. It appears transparent because its cells are non-keratinized at this stage and contain eleidin, which gives a see-through look. This layer sits between the stratum granulosum and the stratum corneum and provides an extra barrier and smoothness for areas like the palms and soles. The other terms aren’t epidermal layers—the stratum corneum is the outermost layer, while dermatology and trichology are fields of study, not skin layers.
