May cause irritation.
Initially, it was great, so much so, I ordered two more to have on hand. About a week or so I noticed that my armpits were black and felt and looked raw, after taking off the dead skin that appeared to be burnt. I did notice that it felt a little tingly but didn't realize that I had an allergic reaction to it. Unfortunately, I waited too long to return the two new ones. That means I'm out of 45 dollars total, for the three. It's a shame but it's my fault. I took the time to read every or most of the reviews and somehow missed the one that states the same issues I had. Not sure if it posted after the fact.To be sure, I tried it a few other times and the same result. Not sure which ingredient caused the problem except maybe the sodium bicaronate. Try at your own risk!
