Methods: A blind and randomized clinical trial, both sexes, aged 18 till 40 years old, subdivided in group 1 (blue LED, 16’ session) and group 2 (blue plus amber LED, 32’), treated for 6 sessions, using specific questioners to psychosocial evaluation, reduction lesions number and evaluation developed by the researchers.

Results: A total of 10 subjects, obtaining improvement in psychosocial impact decreased 1,7, facial perception decreased 2,1 and lesions count, 60% mild improvement and 10% moderate improvement. Conclusion: It is observed that the use of LED technology for acne approach is effective to both groups, as much in self evaluation of improvement as in remission of lesions number, being a secure and effective therapy for acne management.
