what is acne vulgaris

Acne vulgaris is a common chronic skin disease involving blockage and/or inflammation of pilosebaceous units (hair follicles and their accompanying sebaceous gland). Acne can present as noninflammatory lesions, inflammatory lesions, or a mixture of both, affecting mostly the face but also the back and chest

Most people with spots have a medical condition called acne vulgaris. Vulgaris is the medical term for “common”. It is given this name to distinguish it from less common variants of acne .

You may prefer to call acne “pimples”, “spots” or "zits

Acne most often affects the face, but it may spread to involve the neck, chest and back, and sometimes even more extensively over the body.

Individual lesions are centred on the pilosebaceous unit, ie the hair follicle and its associated oil gland. Several types of acne spots occur, often at the same time. They may be inflamed papules, pustules and nodules; or non-inflamed comedones and pseudocysts.
