A total of seventy six patients with mild to moderate acne were recruited in the present study. Among these patients, 36 (47.37%) were in the group treated with SP-NLC gel (group A) and 40 (52.63%) were in the group treated with SP-ALC gel (group B). In group A, thirty three (91.66%) were female and three (8.34%) were male; in group B, there were thirty seven (92.5%) female and three (7.5%) male participants. Among the 36 patients in group A, six (16.66%) patients were excluded from the study for reasons cited as “personal reasons”. Personal reasons were cited for four patients (10%) in group B. There were also six (15%) patients excluded for allergy reasons in group B. Hence, 30 patients in group A and 30 patients in group B were assessed for up to 8 weeks of treatment. The minimum and maximum age in group A were 11 and 38 years, respectively; and in group B these values were 8 and 34 years, respectively. There were no significant differences between patients’ age in the two groups (p = 0.232). At baseline, no significant differences were noted between groups in terms of mean total lesion score (P=0.596). This similarity was observed between groups in the mean inflammatory lesion score (P=0.988) and the mean non- inflammatory score (P = 0.811) as well (Table 1).
