A very common skin condition, acne tends to appear during adolescence due to an increase in hormones during puberty, but can affect people of all ages. Acne occurs when oil clogs the pores of the skin, and is typically experienced in areas with the highest oil production, including the face, neck, shoulders, chest and back. In addition to hormones, acne can sometimes result from oil from skin care products, friction and pressure from sports helmets or equipment/backpacks, squeezing or picking at blemishes, and stress.
