Acne is a skin condition consisting of pimples, deeper lumps (cysts or nodules) and plugged pores (blackheads and whiteheads) that occur on the face, neck, chest, back, shoulders and upper arms. Acne usually begins in puberty, but the condition is not restricted to any age group. Adults in their 20s, 30s, 40s — even into their 50s — can develop acne.
