Apple Cider Vinegar on my beauty mark. Any suggestions?

Hello, my name is Diane and I have had a lightish brown beauty mark on my nose for as long as i can remember and i felt very insecure about it throughout high school, i encountered the apple cider vinegar test and thought what is the worst that can happen.The beauty mark grew bigger and darker on day two and three and it looks like a scab but it barely feels like one.It started burning when i put more apple cider vinegar on. Is this normal?
