Comedolytic activity was assessed in acne patients by determining the reduction in facial microcomedones using the cyanoacrylate follicular biopsy technique. Microcomedones were counted in five-em squares after 8 to 12 weeks of treatment. Only salicylic acid and tretinoin among seven conventional anti-acne medications were found to possess comedolytic activity. The latter was the more effective.
