After reading all kinds of glowing reviews for this product, I was eager to try it! I followed the instructions carefully, using it about once a week and starting with just one minute of time on my skin, and gradually working my way up to about 7 minutes.I have some minor acne, and a problem with clogged pores, but unfortunately this product did not seem to clear my skin at all, even after several months of use.PROS: Very clear instructions, cheap enough that even though it didn't work for me, I don't feel like I got ripped off!CONS: BURNS when you rinse it off, causes some redness, and DIDN'T clear my acne.Bottom line - it didn't work for me, but it was worth a try!
