What term describes structural changes in the skin caused by injury or disorder?

The term that describes structural changes in the skin caused by injury or disorder is "lesions." Lesions refer to any abnormal change in the structure of the skin, which can occur as a result of various factors, including injuries, infections, or dermatological conditions. These changes can manifest in several forms, such as sores, wounds, bumps, or rashes, representing the visible evidence of an underlying condition or injury to the skin.

Understanding lesions is vital in esthetics practice because they can help professionals identify skin issues and tailor appropriate treatments. For instance, recognizing whether a lesion is benign or indicative of a more serious skin disorder is critical for both the safety and care of clients. With the knowledge of lesions, estheticians can make informed decisions regarding skin health and recommend the right products or treatments to promote healing or improvement.

Other terms listed are related but do not encompass the broader concept of structural changes effectively. Excoriation involves a specific type of skin abrasion, inflammation refers to the body’s response to injury or infection, and infections pertain to the invasion of pathogens in the body, which may not directly imply structural changes on the skin itself.
