I loved this product!! I got a bicep tattoo and used this product. I wrapped my bicep an hour and a half before I had to go to the tattoo parlor with plastic wrap and a extremely generous amount of the numbing cream. (I’m talking about my arm was white from the cream, I didn’t even rub it in. I put globs of the cream on my arm) I kept thinking the cream wasn’t working but as soon as I took off the plastic wrap off my bicep I was completely numb. It was crazy!! The numbness worked almost through the whole tattoo. I think my problem was that I took off the wrap as soon as I got to the tattoo parlor which it took 45 minutes to set up and start the tattoo so I think if I would have waited to remove the plastic wrap until he was ready that the numbing cream would have worked the entire time. I was watching a movie on my phone and about 45 minutes passed and still didn’t feel anything. I definitely recommend buying this product.
