What are blisters medically referred to as?

Blisters are specifically referred to as vesicles in medical terminology. Vesicles are small, fluid-filled sacs that can develop on the skin due to various factors such as friction, infection, or allergic reactions. Understanding this terminology is crucial for estheticians, as it helps in accurately identifying and describing skin conditions during assessments and treatments.

The other terms in the choices represent different types of skin lesions or conditions. Macules are flat, discolored spots on the skin that are not raised or filled with fluid. Nodules are solid, raised bumps that are often larger and deeper than papules, which are small, raised bumps that can be either flat-topped or rounded. Knowing these distinctions helps in proper skin analysis and ensures effective communication within the skincare field.
