Which term describes non-inflammatory acne lesions commonly referred to as blackheads?

The term that describes non-inflammatory acne lesions commonly referred to as blackheads is "open comedones." Open comedones are formed when hair follicles become clogged with keratin and sebum, and the surface of these clogged pores remains open. The oxidation of melanin in the sebum causes the characteristic dark appearance associated with blackheads.

Understanding the nature of open comedones is crucial for estheticians, as they indicate areas where the skin may require specific treatments for exfoliation and cleansing to help prevent the development of further acne lesions. This knowledge is essential for providing effective skincare recommendations and treatments to clients.

In contrast, closed comedones (often known as whiteheads) are similar but occur when the clogged pore is closed, resulting in a small white bump on the skin's surface. Pustules are inflamed lesions that contain pus, typically red and swollen. Microcomedos are the early, microscopic stages of comedone development that can be difficult to see without magnification. Understanding these different terms and their implications in skin health helps in accurately diagnosing and treating various forms of acne.
