Acne vulgaris is a common skin condition, affecting over 85% of people. Because of its effect on quality of life, acne vulgaris is more than a merely physiological or cosmetic entity. Acne is caused by changes in the pilosebaceous units. Patients have excess sebum production and non-inflammatory follicular papules. Proliferation of Propionibacterium acnes may lead to the formation of inflammatory papules, pustules, nodules and cysts. Topical and systemic drugs have been successfully used in the treatment of acne. However, many people are concerned about the side effects of these medicines, especially younger patients. Recent reports demonstrated that sequential treatment with laser- and light-based devices lead to a clinical improvement in acne. The rapid clearance of acne lesions is particularly of interest to patients and physicians. These devices include a 532 nm potassium titanyl phosphate laser, a 585 nm pulsed dye laser, a 1450 nm diode laser, a 1540nm Er : glass laser, a 1320 nm Nd : YAG laser, blue light and photodynamic therapy. We performed an open study of fractional 1320 nm Nd:YAG laser as phototherapy of acne vulgaris. This treatment was shown to be effective and well tolerated by patients.
