There isn't one single scientific name for dead skin, as the term encompasses various stages and locations within the skin's structure. However, several terms describe aspects of dead skin cells and their processes:
Understanding Dead Skin
-
Stratum Corneum: This is the outermost layer of the epidermis (the skin's top layer) and is composed primarily of dead keratinocytes (anucleate squamous cells) that form horny scales. Anatomy, Skin (Integument), Epidermis - StatPearls - NCBI Bookshelf These cells are constantly shed through a process called desquamation.
-
Desquamation: This is the scientific term for the natural shedding of dead skin cells from the stratum corneum. Desquamation - Wikipedia It's a continuous process, crucial for maintaining healthy skin.
-
Eschar: This refers to dead tissue that can form on the skin, often as a result of a burn or other injury. It's different from the normal, continuous shedding of dead skin cells in the stratum corneum. Eschar removal is sometimes necessary in medical treatment. Eschar is dead tissue that falls from healthy skin. Learn about causes and treatment.
-
Xerosis: This is the medical term for dry skin, often resulting from a deficiency in dead skin cell shedding and moisturizing. Dry Skin (Xeroderma): Symptoms, Causes, Treatment & Prevention
In summary: While there's no single scientific name for all dead skin, "stratum corneum" specifically refers to the layer of dead skin cells forming the outermost skin layer, and "desquamation" describes the process of their shedding. The term "eschar" refers to a specific type of dead skin, often resulting from injury. The condition of excessively dry skin is clinically referred to as xerosis.
