The pH scale ranges from 0 to 14 based on how acidic or alkaline something is – anything below 7 is acidic, while a number above 7 is alkaline (or basic). Pure water has a pH of 7, which is neutral. You might be surprised to learn that skin does not have a neutral pH. In fact, pH can vary based on the part of the body, and even from person to person. Summer’s Eve®’s pH-balanced Cleansing Washes and Cleansing Cloths are formulated especially for the external vaginal area. A healthy external vaginal area, or vulva, by definition, has an acidic pH. The acidic nature is important to your body’s natural defense and maintaining a good environment for a healthy external vaginal area. That’s why it’s so important not to use ordinary soap in your external vaginal area, since the pH of ordinary soap, can actually be very basic (high pH) and may not complement the natural pH range of your external vaginal area. Basically, you want to cleanse with a product that matches a woman’s external vaginal pH range and Summer’s Eve® Cleansing Wash does just that!
