Which layer of skin is referred to as the Stratum Corneum?

The Stratum Corneum is indeed referred to as the top layer of the skin. This outermost layer is composed primarily of dead skin cells that have become flattened and keratinized, forming a protective barrier. As a vital part of the epidermis, the Stratum Corneum plays a crucial role in protecting underlying layers of the skin from environmental damage, pathogens, and moisture loss.

Additionally, this layer is essential for maintaining skin hydration and overall health. It continuously sheds and regenerates, making it a dynamic component of the skin's overall structure. Understanding the characteristics and functions of the Stratum Corneum is vital for estheticians, as it informs practices related to skin care treatments and products.
