I have done laser hair removal in the past so I knew what to expect. My previous treatments only got about half the hair because I didn't go back for another round due to cost. I was skeptical about Nood, wondering how strong of a laser it would be, but by the 2nd week I started to notice the lack of hair! It's not the most painful thing to do. I liken it to snapping a rubberband on my wrist. It's fast and stings a little, but IT WORKS! I have treated my upper lip and lower lip and chin with Nood. I'm only 3 weeks in now, but I haven't seen any dark hairs. I still have the baby fine light hairs as I expected, but the darker hairs are GONE! I'm very pleased with the results and am looking forward to treating other, more stubborn, areas!
