This came in my September box and I finally got around to trying it last night. The skin on my face is crazy sensitive. When I was a kid, I couldn't get face paint at fairs or birthday parties because the paint would leave a burn mark on my face. (Yes, even though it was listed as "hypo-allergenic")
Anyway, I'm always wary of exfoliants because of the way my skin reacts. Since this was listed as great for sensitive skin and gentle, I thought I would give it a go. Less than a minute after putting it on my face, I could feel the heat build up. Sure enough, when I looked in the mirror, my face was bright red. It was as if I had spent all afternoon in the sun with no sunscreen. I quickly rinsed it off my face. I don't think it was on long enough to do any major damage, but even this morning, my face still feels warm to the touch and is much pinker than usual. So if you have extremely sensitive skin, use with caution.
