Review (1/5): No amount of warning is enough with this product
I followed the directions exactly, testing the product on two areas. Well, guess what, you can have an area right next to the area you tested that will get irritated. Actually, irritated is the wrong word, burned is more correct. As in, burned so badly that you need to use first aid cream on it and it takes 10 days to heal the open skin. Feel sexy now? There may be some people for whom this product works flawlessly. But if you aren't one of those people, seriously, watch out. I don't know how I could have been more careful in my application.
UPDATE (7/7/12): I just wanted to follow up how careful you should be if you choose to use this product. I have light scarring on my abdomen, not a particularly sensitive area, which appears to be permanent.
