What are excoriations a result of?

Excoriations are a result of the manipulation of primary lesions. When an individual scratches or otherwise disrupts a primary skin lesion, such as a blister or rash, it can lead to erosion of the skin's surface, which is medically referred to as an excoriation. This mechanical action can expose the underlying layers of skin, leading to redness, inflammation, and potential secondary infections due to the disruption of the protective barrier of the skin.

This understanding highlights the importance of managing primary skin lesions properly to avoid further complications like excoriations. In contrast to other options, such as infections from secondary lesions, genetic skin disorders, or allergic reactions, these are not direct causes of excoriations but rather represent different pathways of skin conditions or responses.
