Which layer of skin is also known as the horny layer?

The stratum corneum is commonly referred to as the horny layer of the skin. This outermost layer is made up of dead keratinized cells that serve as a protective barrier against environmental hazards, pathogens, and moisture loss. It plays a crucial role in maintaining the skin's overall health and integrity. The term "horny layer" originates from the tough, keratin-rich structure of these cells, similar to the composition of horns in animals.

This layer helps to shield the underlying layers of skin from damage while also participating in the process of desquamation, where dead skin cells are continuously shed and replaced. Understanding the function of the stratum corneum is essential for those in the skincare and waxing industries, as it directly relates to techniques that affect the skin's surface and overall health.

The other skin layers mentioned, such as the stratum lucidum, stratum granulosum, and stratum germinativum, serve different functions in the skin. For instance, the stratum lucidum is a thin, transparent layer primarily found in areas of thick skin, such as the palms and soles, while the stratum granulosum contains cells that begin the process of keratinization. The stratum germinativ
