Well, I'm new here but not to the supplement world. For acne: use Silver Mountain Minerals ( http://www.silvermtnminerals.com/products/silver-topical-gel
) My 3 kids have used many things but this has been the only one to work, it's cheap, no problems and keeps the acne away from face, neck, shoulders, etc. I highly recommend it. You can pick it up on Amazon as well. We did try others but the potency is not the same, although a lessor potency than this may work, it didn't for us.

Also contains: Rosemary, Tee Tree, Oregano, Eucalyptus and Peppermint.

We were using Nutronix silver gel, but it comes out of China and all of the sudden did not work anymore. The only advantage was that it could be used in spots like the mouth/gums where the other oils don't taste good.

Hope this helps, it sure helped my kids.
