Apple Cider Vinegar. Some say it's toothpaste, but I tried it, and it's apple cider vinegar as the 8hr acne treatment. After some recent reading about all the positive effects from ACV uses, I tried it last night on some oh so clogged pores that came out of the sky like lightening on a sunny day. And it worked like a charm. Next up for my ACV trial: Cures and Weightloss. I'll keep you posted.
