The acid test: why vaginal acidity is a good thing

As we mentioned in our need to know  section about intimate biology, the vaginal microbiome is populated by one type of good bacteria in particular: Lactobacillus, which produces lactic acid. 

Lactic acid protects us from a range of pathogens 4, limiting their growth and their ability to cause infections. 

A healthy vaginal tract has a pH that differs slightly, depending on your life stage. It can range between acidic (pH 3.5-4.5) for women of a fertile age, through to near neutral (pH 6.5-7) for those who are menopausal.12

This pH-balanced environment keeps our intimate areas protected, healthy and comfortable.

But if the pH is upset, becoming more alkaline, we can experience soreness, discharge and infections (known as vaginal dysbiosis). Many factors can disrupt pH4 we talk about the the most common ones here.

All Intibiome intimate washes are carefully developed to suit the intimate area needs of women –  at different life stages and with different lifestyles.
