Review title is Mixed review - read for thoughts/cautions [SEP] Very hard to write a fair review on this product.  (1) yes, it will activate the peeling of a layer or two, and usually with in a couple of days, (2) product design is a bit cumbersome to use (a plastic bag bootie that has the ooze inside that is a bit of a struggle to get on your foot, and (3) because the goo inside is all over the plastic bootie, it not only gets on the bottom of your feet, but all over your entire foot (bottom, top, ankle, etc.).  As a result of #3, not only did my entire foot feel tight and tingly for days, but the product created a very irritable rash on the tops of my feet. The rash has been there all week and still hasn't subsided.  This would be a much better product if you could just put it on the bottoms of your feet or where the dry/calloused skin is.  If I every use it again, I will put it on a plastic mat or something and just allow the bottoms of my feet to be exposed to the goo or rub it on the needed areas with a plastic glove.  NEVER again will I put it on as a sock/bootie and now I just hope the tops of my feet heal.  (I put the product on Saturday evening, the attached photo is from Wednesday and the top of my feet look worse today, Friday)
