Mandelic Acid...I am taking the plunge! in General acne discussion Posted July 31, 2008 So I have been doing the MA for 2 weeks now. I had to reduce to once a day in order to halt the peeling. I LOVE jojoba oil, but do feel it is a tad greasy to put on and then head to work. But my skin feels good. Yet...I have high expectations and I don't see these blackheads disappearing. What should I expect to see and in what timeframe???
