I had a mole on my face which I really hated and read online that apple cider vinegar could be applied to remove it. Stupidly I did this and what I've been left with is so, so much worse than before and I now have a large unsightly hole on my face but with raised edges, it hasn't improved in 18 months. Please can someone recommend a treatment to fix this urgently as I'm now more self-conscious than ever and it's really getting me down!
