Total 105 patients were included in the study by non-probability consecutive sampling. The patients undergone 16 sessions of blue light for 15 minutes each, twice a week for 8 weeks. Global Acne Score (GAS) was calculated at the start of the treatment and at 8 weeks. Mean reduction in GAS was measured. The statistical analysis was performed using SPSS version 16.

 

Results 91(87%) patients were between 15-30 years of age while 14 (13%) were between 31-45 years of age with mean age of 22.90±5.97 years.  28 (26.7%) were male and 77 (73.3%) were females. Acne was mild in 50 (47.6 %) patients and moderate in 55 (52.4%). Pretreatment mean global acne score was 18.9905±6.24884 and posttreatment mean global acne score was 15.1143±5.1143. Mean reduction in global acne score after 08 weeks was 3.87619±3.33021 (p <0.0038).
