Abstract
Objective To assess the efficacy and safety of various spectrum lasers in the treatment of acne vulgaris. Methods Based on the principles and methods of Cochrane systematic reviews, we searched the Cochrane Library (2009, 6 issues), PubMcd, Embase, China Biomedical Literature Database, China Journal Full Text Database, Chinese Scientific Journals Full Text Database. Retrieval time was up to June, 2009. Randomized controlled trials (RCTs) of lasers for acne vulgaris were included. Results Twelve RCTs totaling 367 patients were included. Because the lack of clinical homogeneity, only descriptive analysis was conducted. Acne lesion counts improved significantly with laser therapy. Adverse effects were limited to transient erythema and edema at treatment sites. Treatment-related pains were well tolerated. Conclusions Current evidence demonstrates that all type lasers in treating acne vulgaris is safe and efficacy. However, higher quality RCT research would be needed to verify the effects and status of lasers on acne vulgaris. Key words: Acne vulgaris; Lasers; Randomized controlled trials (RCT); Systematic review
