I went ahead and used a full finger's length of benzyol peroxide morning and night. Perhaps I went too fast, but it's done now. The condition of my skin today was as follows: Skin feels rough and the dryness is definitely kicking in, especially around my eyes and mouth. I'm not seeing any flaking yet, but the dryness is causing the very surface of my facial skin to be tight and move unnaturally when I contort my expression. I'm pretty sure that this tightness is what precedes the flaking period.
