One of the most common skin conditions, acne is a disorder of the hair follicle or pore, resulting in pimples, blackheads or whiteheads. While acne most commonly occurs around and on the face, it can also affect the neck, chest, back, shoulders and upper arms, with rare outbreaks on other parts of the body. Acne occurs when pores are clogged with oils and dead skin, creating a bacterial infection resulting in an acne "breakout" commonly accompanied by inflammation and redness. Acne most commonly affects teens and preteens, due to hormonal changes in both boys and girls during puberty, but many adults also suffer from acne, as well as some babies, toddlers and children. A number of treatment options are available for mild to severe cases of acne. But no matter the severity of the condition, all treatments begin with good daily skin care. Choose from an array of sprays, sticks, gels, lotions and pads, night creams, spot treatments, concealers and healers. There are also products available for post-acne treatment to promote a more even complexion.
