I paid for it because it was cheap with a 5-episode event. When I first got it, I was shocked because it hurt so badly. It felt like I was putting a sewing machine on my armpit. Even though I have thin hair, I was shocked by how painful it was. (I had received it once at another hospital before, but at that time it was just stinging.) Fortunately, the hair was really reduced, but I was so afraid of the pain, so I asked for an anesthetic cream and they said they would spray anesthesia. I was doing laser while applying spray anesthesia... I got a first degree burn . Be careful everyone.
