I got the white Castile figuring 5.6 was fine. I'm also going to try the DianaYvonne AHA cleanser since it's 5.5 PH, no detergents, and all the ingredients seem fine (it does have oils, but I'm up for trying it).
Basically forehead's been broken out for a month now. I'm fine with a few since I work with a bandanna and I'm sure that contributes, but I've never had this bad a breakout in all the years I've used the GCC. They're small, so not terribly noticeable, but definitely out of the norm. I've also had some small zits on my cheeks. Not quite as much as my forehead, but also more than I'm used to. The only change is PSF's foaming cleanser instead of the GCC.
