What are urticaria commonly known as?

Urticaria is commonly known as hives, which are raised, itchy welts on the surface of the skin. This condition typically results from an allergic reaction, stress, or other irritants that cause the release of histamine in the body. The histamine prompts fluid to leak from blood vessels into the skin, leading to the characteristic swelling and redness that defines hives. Understanding urticaria is important for estheticians, as it can impact skin treatments and products used on clients with sensitivities or allergic reactions.

Rashes, blisters, and warts are distinct skin conditions and do not describe urticaria. Rashes are broader and can result from numerous causes, blisters are fluid-filled sacs that arise due to friction or burns, and warts are benign growths caused by the human papillomavirus (HPV). Recognizing the difference among these conditions helps in providing proper care and treatment in esthetic practice.
