Good question. “pH-balanced” means that The Cleanse won’t change your skin’s natural pH—we clinically tested it to make sure. Skin’s happy place is a pH of about 4.5 to 5.5. If your skin’s pH becomes too high or too low, it can weaken its protective barrier and open the door to dryness, irritation—even acne. A pH-balanced cleanser is key to maintaining a healthy pH, which is why we created The Cleanse.
