acne vulgaris
Quick Summary
Acne vulgaris, commonly known as acne, is an inflammatory skin condition affecting the sebaceous (oil) glands. It typically begins during puberty due to increased male sex hormones stimulating overactive oil glands.1
The primary lesion is the comedo, or blackhead, which is a plug of sebum, dead skin cells, and bacteria within a hair follicle. These can be open (darkened) or closed, potentially leading to deeper inflammation.1
Acne is graded based on severity, from mild (comedones only) to severe (deep nodules and scarring). Treatment options include topical medications like benzoyl peroxide and salicylic acid, antibiotics, and hormones. While variable, acne often resolves spontaneously over time.12
