comparison of topical herbal cream and 1% clindamycin gel for treatment of mild-to-moderate acne: a randomized clinical trial

Background: acne is the most common chronic skin disease affecting young adults and adolescents worldwide. a characteristic of this disease is the chronic inflammation of sebaceous glands leading to comedones, papules, pustules, nodules, and cysts. topical and systemic uses of medicines are common approaches to treat acne. however, these medicines are associated with some adverse effects and increased microbial resistance. objectives: we aimed to prepare and apply an herbal formulation containing several herbs with different effects on mechanisms associated with acne formation.methods: in this study, 66 patients with mild-to-moderate acne randomly received a packet containing herbal medicine or clindamycin gel. the treatment period was two months, and the total acne lesions and acne severity index were measured every four weeks. after eight weeks of treatment and follow-up, the physician examined clinical outcomes and possible complications. results: decreases in total acne lesions and acne severity index were significantly different in both treatment groups (p < 0.05 in both groups). although the herbal cream provided better improvement than clindamycin, there was no significant difference between the two groups (p > 0.05). conclusions: the use of the herbal cream could be recommended for treating acne lesions due to few complications, greater patient satisfaction, and avoiding microbial resistance to chemical antimicrobials.
