I was about to give up on the regimen after it appeared not to be working, but incredibly, I now seem to be getting clear skin, and haven't had a cyst in weeks.
I think it's because I started using a larger quantity of BP than before, and kept using large quantities on clear areas.
And I think it's working because even after a couple of nights out drinking alcohol, and stressful weeks at work, still no cysts.

I've been using 5% up til now because 2.5% wasn't previously available where I was living. I plan to change to 2.5% after this tube runs out, but I'm curious to know whether using the same quantities I've been using at a lower concentration will give the same results. Strange that a 'small' amount of 5% wasn't good enough, yet I hear that 2.5% is supposed to be just as effective.

Anyway I've been using more moisturiser too, since I'm worried that all this BP might otherwise damage my skin.
If I want to try vitamin c serum for the scars, do I apply it between BP and moisturiser?
