I put the product on and let it sit as the instructions advised. Things were okay for a few seconds, and then … THE BURNING! I have certainly felt worse, but it was very noticeable. The instructions assure me that this burning is “due to the ingredients reacting to your bodies own PH balance which is normal and will go away upon rinsing off the colorant.”Rinse it off I did, and did I notice a difference? I did not. I will confess to you I took before and after pictures for my own scrutiny. Well hello there my vulva. Long time, no see. Sorry about the burning sensation … In summary, I would file this with magic creams that purport to take twenty years off: don’t bother. And don’t think so hard about your vulva, either. Just enjoy it.
