Which layer of the skin is known as the outer layer that can be touched?

The epidermis is recognized as the outermost layer of the skin, which is the primary barrier between the body and the external environment. This layer is composed of tightly packed cells that form a protective layer, shielding the underlying tissues from pathogens, chemicals, and physical damage. The epidermis is also the layer that can be directly touched and felt, making it critical for sensory perception.

Furthermore, the epidermis plays a vital role in functions such as moisture regulation, UV protection, and overall skin health, as it undergoes continuous regeneration. The presence of melanin, which gives skin its color and protects against UV radiation, also resides within this layer. Understanding the role and characteristics of the epidermis is essential for those training in skin care and aesthetics, particularly in the context of waxing and other treatments that interact directly with this outermost layer.
