The study conducted in sixty patients. Group A (case) 20 patients were treated with adapalene and benzoyl peroxide combination gel, group B (control) 20 patients were treated with topical adapalene and group C (control) 20 patients were treated with topical benzoyl peroxide. The side effects experienced by patients of different groups in their first follow up were noticed. In group A - erythema, scaling, dryness, burning and pruritus were present in 45%, 10%, 35%, 40% and 10% of patients and in group B, 35%, 25%, 30%, 35% and 15% respectively. However in group C dryness and pruritus were absent in all the patients and the erythema, scaling and burning were 30%, 25% and 25% respectively. In 5^th follow-up visit, in group A- erythema, scaling, dryness and pruritus were present in 15%, 5%, 15%, and 5% of patients respectively and burning was absent in group A. In group B erythema, scaling, dryness, and pruritus were 15%, 5%, 5% and 5% and burning was absent in group B.
