In short it doesn't exactly tickle and feel good. Don't let other laser hair removal centers fool you with lies and hype. It's next to impossible to tell you how the laser will feel on your body, since every single person has a different pain threshold and reaction to the laser. Many people say it feels a lot like getting a tattoo, others say it feels like being snapped by a rubber band and others say they can barely feel the laser at all. Topical anesthetics are sometimes used to make the laser hair removal treatments more comfortable and it's possible (you would have to ask them) your doctor could prescribe you a mild pain killer as well for the laser hair removal treatments. Please don't come in drunk though, if you think that will help with your pain tolerance. This isn't a tattoo parlor after all.
