Desquamation is the term used to describe the process of shedding or peeling of the outer layer of the skin, specifically the stratum corneum, which consists of dead skin cells. This natural process is crucial for maintaining skin health as it allows new cells to replace the old ones, helping to prevent the buildup of dead skin and potentially reducing the risk of skin problems, such as infections or clogged pores.

In contrast, exfoliation typically refers to the cosmetic process of removing dead skin cells through mechanical or chemical means, but it can also encompass the natural desquamation process. Induration refers to the hardening of tissue, often due to inflammation or disease, and erythema describes redness of the skin, usually resulting from increased blood flow due to various stimuli.
