Who gets acne vulgaris?
Nearly all of us have acne at some time or another. It mainly affects adolescents (and can start as young as 8 years old), but acne may persist, begin or become more severe in adulthood.
What are the clinical features of acne vulgaris?
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.
