weird. what was it? I had a perscription cream, 2 actually, a bleach and an acne cream. Using them both caused redness and some stinging, but it only was really painful if I was hot and sweaty, then I couldn't get to a sink fast enough to rinse off my face...the burning and stinging was awful. It also bleached my towels and my pillowcases and any clothes that it got on (see sweating above, lots of bleached out drip marks on my tee shirts). It wasn't worth it IMO, it worked, no pimples and the dark spots were fading, but my face felt raw and was bright red instead. I'll just deal with the pimples and spots.
