Which component is NOT typically found in the dermis?

The stratum corneum is the outermost layer of the skin's epidermis, not a component of the dermis. This layer consists of dead skin cells that provide a protective barrier to the underlying layers. The dermis, on the other hand, lies beneath the epidermis and contains several key structures, including blood vessels, nerves, and arrector pili muscles, which are responsible for raising hair follicles. This distinction is vital for understanding skin anatomy and functions, especially for those working with waxing and skin treatments, where knowledge of skin layers is essential for effective and safe practices.
