We were given this spray when my daughter had her ears pierced. It worked like a charm and she did not have any infections from her piercings. We brought her to a tattoo parlour to have her ears pierced. I did not want her to have her ears pierced with a piercing gun that leaves a jagged hole and the store nearby only had one gun and I was sure that if she had one ear pierced that she would not sit there for ear number two. The tattoo artist measured her ear with a ruler and did an excellent job with the hole placement. She used a needle and the piercing was quick. My daughter did not cry once and felt no pain. She's one tough cookie.
