I use the scrub for nearly a month and have now found my concentration at 40%. Already in the early stages of my skin has improved significantly after the initial aggravation. It has become much more even, smoother and finer. Looking for my personal concentration I have the 40% acid by mistake eight minutes left on it (because I have unfortunately not heard the alarm clock). I immediately neutralized everything and yet it had burned. The next morning I was bright red and had minor burns, in some places was completely from the skin. Since I had already fear that I get scars. I Bepanthensalbe it lubricated and went to the dermatologist on the same day. The prescribed me a cream and after a few days it was normal again and my skin has beautified itself. I hereby would like to say is that you should make it by no means experiments, neither the concentration nor with the exposure time. If ye halt to the instructions, then you will surely achieve a great result and save many costs !!!
Unfortunately, the neutralizer is not enough. But I've read that some Natronlaue take from the drug as a replacement.
I can now go out without makeup, I could never before imagine and I was asked by a couple of friends that I am using a new face cream or powder :) I have already bought my mother and am excited about your score.
