Treatment of Acne Valgaris by 805 nm Diode Laser

Abstract

Acne vulgaris is very common dermatological problem which is disfiguring, it occurs in young age group.

The purpose of this study is to evaluate the therapeutic effect of 805nm diode laser on inflammatory popular type of acne vulgaris.

The sample of study was 30 patients of both sexes, ages varies between 15-32 years, collected at Al-kindy teaching hospital.

The study protocol was the application of laser therapy to acne lesions which was classified according to severity into severe, moderate and mild, considering other side as a control.

The cw diode laser used had the fallowing parameters, 805nm wavelength, and 500Hz frequency, 300 second time, 3W power, and with 1cm distance between the lesion and laser source.

The results were collected for more than 5 weeks and shown that there is a good response rate in the treatment of lesions with diode laser especially in severe and moderate type which shows decrease in severity and numbers of popular acne.

The response of lesions to the laser therapy was with very little side effect in comparison with other treatment modalities, and is disappearing within less than an hour. There is no sex difference related to side effects.

Finally this type of therapy is very effective concerning the response and side effects and hope in the future to prolong the follow up period and larger the number of patients, including different types of acne and using other parameters of lasers .
