What are hives, which are formed when histamines are released in the body, known as?

Hives, which are a result of the release of histamines in the body, are known as wheals. This condition occurs when histamines trigger inflammation and cause fluid to leak from blood vessels, leading to raised, itchy bumps on the skin. Wheals are characterized by their temporary nature; they often appear quickly and can disappear just as fast.

Understanding this term is important in esthetics and dermatology, as recognizing wheals can help practitioners identify allergic reactions or other skin conditions that may require different treatment approaches.

The other terms refer to different skin manifestations: papules are small, raised bumps without fluid, patches are flat areas of skin that differ in color or texture from the surrounding skin, and scales are flakes or dry patches of skin that can occur due to various skin conditions. Knowing these distinctions helps in providing correct diagnoses and appropriate treatments in the field of esthetics.
