How much benzoyl peroxide are you using? Your skin might be reacting to it if you're using too much. Otherwise, the last week and a half or so my skin was HORRIBLY dry; it was scaly and peeling, and I couldn't even open my mouth completely. Just keep doing what you're doing, and I promise it'll go away. Your skin's just adjusting, and it'll be good to shed all of those layers and get everything out in the open to treat You can try exfoliating with some jojoba before cleansing, or reapply as much moisturizer as your skin needs. I even peeled off a few flakes with a tweezer a couple of times (gross, I know haha).

You know, last night I came across someone's suggestion (I couldn't trace back to the original) that I should use jojoba oil to exfoliate my skin gently (with fingertips) before doing the benzoyl peroxide. Instead of this, I did the jojoba oil exfoliation before the cleanser and after the treatment I applied a very generous amount of jojoba-infused moisturizer and my skin was pretty calm this morning. SO much better. I'm going to continue doing this. Oh, and by the way, I'm using a full index-finger's length of benzoyl peroxide morning and night.

-Thanks for your suggestions

Oh, well that explains why you're so dry! Haha there's nothing wrong with using the full amount of BP this early on, but your skin will absolutely be uncomfortably dry because of this. I took 3 weeks to gradually work up to using the full amount. Nonetheless, glad your skin is doing better from the jojoba!
