I had a few blemishes that would not go away! I tried my spot treatment from Murad but it wasn't working. My Sister suggested I try ACV, she has been using it for a few weeks to treat her ance and she has had great results. I used the ACV undiluted on a q-tip as a spot treatment for each one. The next morning I was shocked to see how much they decreased in size and the pain was gone! I would recommend anyone who suffers from acne to at least try it! I purchased a bottle of ACV for $0.99 from my grocery store which is a lot better than the $25 I was spending on my spot treatment by Murad!
