I sent you a message Golden Girl maybe 3dys ago, I'm not sure if I did it right I don't have anything in my sent folder. But I purchased a 70% glycolic acid and it arrived I would like to know how/what to dilute it with to make it 30%, if I do 1/2 cup glyc do I do 1/2 cup water? I don't know? Help. Also how often should I use this 2x a week bi weekly how often?
