Which term is used for a type of acne characterized by blockage of hair follicles?

Comedonal acne is characterized by the blockage of hair follicles, which is primarily caused by a build-up of excess sebum and dead skin cells. This type of acne manifests as open or closed comedones, commonly known as blackheads and whiteheads, respectively. The blockage within the hair follicles can lead to an increase in bacteria, which may result in inflammation and other forms of acne if not properly managed. Understanding this terminology is essential for identifying and treating different types of acne effectively in a cosmetology practice. In contrast, hormonal acne is typically influenced by hormonal changes, aging acne refers to skin changes associated with aging, and dermal acne often pertains to deeper acne lesions, showing that each type of acne has distinct characteristics and causes.
