I've used this regimen off and on for years. I know for sure that BP works for my skin, it's just a matter of being consistent w/ the regimen. I've been back to using it at night for the past 3 weeks. The first 2 weeks I was using Neutragena on the spot. This past week, I start back using Dan's BP gel (which allows me to apply ample amounts) and noticed that it was actually clearing up faster.
So as far as bumps I'm pretty good on don't have too many problems, but I have so many scars that you can't really tell that my skin is clear! Here are pics to prove. Luckily my makeup covers them pretty well, but I want to wake up to beautiful skin too!
