I'm in my fourth week of the regimen and my face is really dry and flaky. Can I cut back on the bp to once per day until the flakiness gets better or I should keep on using it twice a day?
Keep using it twice a day as directed. The dryness and flakes are a sign your skin is getting used to the treatment and lessening the amount would just be a step backwards.
Mine was like that too. I tried using some of my boyfriend's cocoa butter... not much. Just a little bit with the moisturizer and it helped tremendously.
