What Is A Blister
Filed Under Eczema Skin Symptoms, Eczema Symptoms
A blister is a bubble of fluid under the skin. The clear, watery liquid inside a blister is called serum. Allergic contact dermatitis and irritant contact dermatitis are the two types of eczema that do often cause blisters. Most of the other kinds usually do not result in the development of blisters.
Contact eczema (or contact dermatitis) is so called because your skin flares up when it comes into contact with an irritant. Examples of irritants include harsh detergents, solvents, chemicals, latex, nickel or specific plants, for example, poison ivy, poison oak or poison sumac. The ensuing inflammation results in blisters and the bubbling of your skin.
Sometimes an autoimmune disease occurs due to contact eczema which causes blisters to appear on the skin. An autoimmune disease is when your own body turns on itself and attacks your skin. Why this happens is not known.
If a blister remains unopened, serum can provide natural protection for the skin beneath it. Small blisters are called vesicles. Those larger than half an inch are called bullae. A blood blister is filled with blood, rather than serum.
If you start to itch however, you may be tempted to scratch open the blister. This results in cracked open skin, making you more liable to bacterial infection. A bacterial infection can worsen your flare up. You itch even more and find yourself in an itch-scratch-itch cycle that is hard to break.
