You shouldn't use any of those. Just water. It's so bad for your natural pH and can cause infections.

I have had this for three months straight before and I tryed heaps but it's happening less now that I use qv wash but not on the v just water and my hands

I have probs with my ph levels and yeast infections!! I've tried solo much!! Vagisil sensitive is the best!! If you ever get yeast infections, depending on severity, cortisone makes something for vaginal itch and irritation. And diet affects everything! I eat Greek yogurt like it's going out of style at times. Yoplait. All for the V!! 🙌🏼
