"I was using Epiduo for a month with great results. This summer I planned a trip to Europe for 5 weeks. I forgot to pack my Epiduo so I resolved in walking in a pharmacy and asking for Epiduo. To my suprise it was not availble but the pharmacist checked it on the net and on the spot he mixed the old fashion way Epiduo with a small variation. He mixed 4% benzoyl peroxide. Voila much more effective in resolving mount Vezuvius on my face. So Epiduo works but Epiduo and twice the benzoyl peroxide works wonders. He did though warn me of dryness and protection from sun which I did take care of."
