What is pH?
Easy guide to pH levels and why it is important
pH is a measure of how acidic or alkaline a substance is. The pH of a certain substance is described as a number from 0-14. The lower the number, the more acidic the substance. Water is neutral, and has a pH of 7.
The vaginal pH of a healthy vagina is 3.5 to 4.5, which is an acidic environment. You should never wash inside of the vagina since it is self cleansing. The skin of the outer parts of your intimate area has a pH of 5. This part is not self cleansing and therefore you should use an intimate wash with pH 5 to avoid any unbalance of the pH level.
Normal soaps has an pH of 9, which is not recommended for the sensitive skin in the outer parts of your intimate area. This will dry out the skin and result in pH inbalance, and vaginal discomfort.
