Acne

Acne is a skin condition caused by infection of hair follicles and sebaceous glands (pilosebaceous follicles). Hyperseborrhea causes pore blockages, then bacteria (usually Propionbacterium acnes) provokes an infection and transformation into a papule or vesicle. It affects around 80% of adolescents (from age 9-10 in girls, around age 12 in boys) and 10 to 15% of these develop a severe form of acne. (www.medicopedia.net)
