title: Lasers in the treatment of acne.
abstract: Acne is a chronic disease of the pilosebaceous units, presenting as inflammatory or noninflammatory lesions, affecting primarily the face but also the back and chest. The mainstay of treatment remains topical retinoids, benzoyl peroxide, azelaic acid, antibiotics, and isotretinoin, many of which result in poor compliance, lack of durable remission, and incur adverse effects. The use of lasers to treat acne is continuously increasing because of their minimal complications, limited number of office-based treatments required, potential benefits of simultaneously treating acne scarring, and the rapid onset of results. The 1450 nm diode laser, 585- and 595-nm pulsed dye lasers (PDLs), near infrared diode lasers, 1320 nm Nd:YAG laser, 532 nm potassium titanyl phosphate laser, 1064 nm long-pulsed Nd:YAG laser, 1540 nm Erbium (Er):Glass Laser, and the 1550 nm Er:Glass fractional laser are among the most common lasers used to treat acne and acne scarring. These lasers target the underlying causes of acne including the colonization of Priopionibacterium acnes, high levels of sebum production, altered keratinization, inflammation, and bacterial colonization of hair follicles on the face, neck, and back. We review the efficacy and side effect profiles of various lasers used to treat acne.
