Lesions of the skin that develop in the later stages of a disease are classified as secondary skin lesions. This classification is significant because secondary lesions often result from the progression of a primary lesion or due to changes in the skin as a response to an underlying condition. For instance, a primary lesion such as a pustule may eventually lead to a secondary lesion like a crust or a scar as it heals and changes.

Understanding the difference between primary and secondary lesions is crucial for estheticians as it aids in proper assessment and treatment planning. While primary lesions are directly associated with the initial presentation of a skin condition, secondary lesions provide insights into how the condition is evolving over time and its impacts on the skin’s overall health.
