What are blackheads scientifically referred to in the field of cosmetology?

Blackheads are scientifically referred to as comedones. This term encompasses both open and closed comedones, with blackheads representing the open form. When follicles are clogged with excess oil, dead skin cells, and bacteria, they can become enlarged and obstructed. The dark appearance of blackheads is due to the oxidation of the melanin in the skin when it is exposed to air, causing it to turn black.

Understanding this term is crucial in cosmetology as it allows professionals to identify skin conditions and recommend appropriate treatments or products designed to prevent clogged pores and manage acne effectively. The other terms listed refer to different skin conditions: Acne vulgaris generally describes the broader category of acne, sebaceous cysts are closed pockets of tissue beneath the skin, and pustules are inflamed lesions filled with pus. Each term addresses distinct skin issues, making accurate terminology important for proper diagnosis and treatment.
