The pink box is the pH bar and I absolutely love it!!! I had feelings of a possible yeast infection coming on. I ordered the pH soap before, strictly as a preventative measure, but they came just in time for me to need to use them! After using it only 3days, my symptoms were gone and I followed up with a Doctor's appointment, which I was negative for any issues, yeast, BV, etc. I am never disappointed with my Skin Kulture purchases!!!
