What are secondary lesions?

Secondary lesions refer to skin changes or alterations that occur as a result of a primary skin condition progressing. These lesions typically develop over time due to various factors, such as scratching, infection, or natural evolution of an existing skin condition. They can manifest in various forms, including scales, crusts, or scars, and often indicate that a primary skin issue is worsening or changing. Understanding secondary lesions is crucial in the practice of esthetics, as they can reveal much about the skin's health and the underlying conditions present.

The context of the other options helps clarify the distinction: while some lesions can arise from allergic reactions (first option), they do not specifically define secondary lesions. Fluid-filled elevations, which may be associated with certain conditions, represent a different category, typically known as vesicles or blisters, rather than secondary lesions. Rashes that are inherited pertain more to genetic predispositions and initial primary lesions, rather than changes that occur as a result of disease progression. Therefore, the recognition of secondary lesions is essential for providing informed esthetic care and treatment options.
