flaking

This term describes a specific type of degradation where a surface disintegrates into thin, flat fragments. It is most commonly associated with biological tissues, such as dry skin or dandruff, and inorganic materials, such as old paint, rust, or dried mud. The connotation is typically negative, suggesting neglect, decay, or a lack of moisture.

When used as a noun, it refers to the ongoing process of shedding. When used as an adjective, it describes the state of the surface itself. In a medical or dermatological context, it is a precise descriptor for the shedding of the stratum corneum, distinguishing it from "peeling," which often involves larger strips of skin.
