What is a bulla?

A bulla is defined as a large blister that contains watery fluid. This condition typically arises when there is a significant accumulation of fluid between the upper layers of the skin, often as a result of friction, burns, or other irritants. Bulla can vary in size, but they are generally larger than other types of blisters, such as vesicles.

Understanding the context of skin lesions is crucial in cosmetology, as this knowledge aids professionals in recognizing conditions that might affect their clients. For instance, identifying the characteristics of a bulla can help in deciding the appropriate course of treatment or recommending products that will not aggravate the condition.
