I'm into my 3rd week of acne treatments now and I'm definitely still purging. I have 9 little whiteheads, a couple of them inflamed. Although, I'm happy to say that I have no new cysts and the ones I have had are still shrinking. While these little pesky whiteheads are annoying, they aren't bad at all. They will probably clear up in a day or 2 thanks to Differin. It's always the really big whiteheads and cysts/nodules you have to worry about because they take forever to heal and leave nasty scars.
My next Isolaz treatment is on December 1st. Already looking forward to it as it'll be one step closer to finally being clear!!
