Let me say, I did a test patch first with no problem. Today I climbed in the shower and followed the instructions spraying on the foam and leaving it only 4 minutes. It instantly felt cold and tingly, but the cold soon turned to a burning sensation. At 4 minutes I started rinsing off. The hair was coming along with little rolls of skin. All dipilatories take off a layer of skin, but here I am a few hours later with my skin still tingling, feeling sensative hot and uncomfortable.. I would never buy this product again.
