I am shocked products that can do this much harm are on the market. I get that Nail Magic has worked for some, but something that hurts even a few people, and obviously this is the case here, should at least have to disclose that the product could cause mild to extreme pain. I started experiencing severe pain in one of my fingers out of the blue, but assumed it was the change in weather. If you've ever had frostbite, or something close to it, that's what it felt like. But once inside and warmed up, my finger continued to hurt so I had to rule that out. Then there was extreme sensitivity to warm water when I went to do dishes. Odd, I thought. Finally, I woke up in the middle of the night from severe pain in all of my fingertips. I don't have sensitive skin, and it felt like they had been slammed in a drawer. I truly was stumped. If it wasn't the weather, and I hadn't been practicing 'walking on my hands', what was causing the pain? I avoid doctors until I've exhausted all possible options, but I was getting ready to make an appointment when it occurred to me it had to be the Nail Magic. That's the only thing that affected all of my fingers. This was like a chemical burn, and from having used the product just three days and only once a day (versus the twice a day recommended). My suspicion was confirmed when I read similar posts about the product (thank goodness for the internet!). It's been several days since i removed Nail Magic and my fingertips still hurt. To be sure, we all get to decide what products to use on and in our bodies. But you've got wonder why consumer products are not subject to the same scrutiny as prescription drugs which have to disclose possible side effects. At least we'd have knowledge of the risks. You also have to wonder if exposing yourself to a product that contains a known carcinogen (formaldehyde) and that has caused harm to others, is worth beautiful nails, especially when there are other (non-harming) nail treatments out there. We have no control over the air we breathe or other environmental risks, but we do have control and choice about the products we use in and on our bodies.
