blister
This term describes a localized separation of skin layers or surface coatings, creating a fluid-filled pocket. It carries a strong connotation of irritation, damage, and physical discomfort, often associated with friction or thermal trauma. When applied to non-biological surfaces like paint or varnish, the word shifts from a medical context to a structural failure. In these cases, it implies a loss of adhesion and a degradation of the protective layer due to environmental stress.
