I Used Veet Hair Removal "down There" It's Been Burning

I used veet hair removal "down there" it's been burning & extremely itchy along the inside of my vagina. I have been putting lotion & after a week, it's slightly better. My vagina is extremely dry now which cause itchy fruction unless I'm using the lotion. This is week 2. How long will it take to heal the inner vagina? Should I pick up polysporn or anything else. Using preparation H tonight on it so I can try to sleep.
