My skin type is dry and closed comedones for almost a year now. It's on my cheeks and my forehead is full.    What should I use for treatment? What I'm using:    Benzoyl Peroxide 2.5% gel:  For the past week, I have been applying it for 2 hours only on affected areas and then I wash my face.   Adapalene: After I wash my face, I apply a very little amount of it and follow up with Cetaphil moisturizer. Salicylic Acid-  Facewash: I have finished a bottle of it. I've switched to Cetaphil facewash for now to avoid irritating my dry skin in winters. Zitcare (1% salicylic acid): On days I don't apply adapalene, I apply zitcare and follow it up with the Cetaphil moisturiser. In the past month, they have increased which is why I started Benzoyl Peroxide last week. I have noticed they've become more prominent since I have started Benzoyl Peroxide. I read that it's supposed to purge before it gets better with Benzoyl Peroxide. What should I do?
