What is the term used for a skin lesion in its early stages?

The term used for a skin lesion in its early stages is primary lesion. Primary lesions are the initial manifestations of disease and appear as a direct result of a specific condition. They have distinct characteristics and include various types, such as macules, papules, vesicles, and pustules. Recognizing primary lesions is crucial for accurate diagnosis and treatment, as they reflect the original event leading to skin changes.

Other terms refer to different stages or types of lesions. Secondary lesions, for example, develop as a consequence of primary lesions, indicating a progression or change in the condition. Pustules are a type of primary lesion that contain pus and generally indicate inflammation or infection. Vesicles are small, fluid-filled blisters that can also be categorized as primary lesions but describe a specific subset within that classification. Understanding these definitions allows estheticians to effectively assess skin conditions and tailor care accordingly.
