Reading this forum and other places, there's not really a consensus on whether BP should or shouldn't be applied to a healing 'wound'. I, personally, find it helps with the healing time - and it definitely for me helps with fading the residual red mark, but I think everyone has their own opinion on this matter
Whenever I'm unfortunate to have a breakout which has been severe enough to cause any bleeding and ultimately scabbing, I usually apply the BP as normal, then use a very thin layer of Sudocrem directly on top of the scab before I go to bed.
I'm on my 5th day back on Epiduo, and with using just three pumps (about a peanut M&M amount of gel) I am already having really fantastic results. I have mild, to moderate acne around my shaving line on my neck, and infrequent, but fairly nasty, breakouts on my chin & sometimes forehead). I'm almost completely clear, having not had a new pimple for 3 days, and the existing spots are fading very nicely indeed. My skin is looking smoother, and not red to the point that it is noticeable to anyone other than me. Hooray!
