What is a bulla?

A bulla is defined as a larger blister that forms when fluid accumulates between the upper layers of the skin. Typically, bullae appear as raised areas on the skin, often filled with clear fluid, and they can vary in size, generally measuring more than 0.5 centimeters in diameter. Understanding the characteristics of a bulla is important in the context of nail technology, as it can relate to various skin conditions that may affect the nails and surrounding areas.

Recognizing the distinction between blisters is crucial in identifying skin issues; while a small blister refers to a smaller fluid-filled lesion, a bulla indicates a more significant accumulation of fluid, typically resulting from friction, burns, or underlying medical conditions. Knowledge of such terminology helps in effectively communicating and addressing skin-related concerns in a nail technology practice.
