I don’t doubt that it works. It definitely will take A LOT of sessions and each session can take up to 30min+ depending on how many areas you want to treat. I have medium-light skin and dark brown hair. This still hurts to use on settings 6 or 7 (the recommended setting to see results). I tried OTC numbing gel and it was still uncomfortable. I have had laser hair removal at a dermatology office and it was a much faster process. It was also painful, but they gave me a prescription numbing gel and the session was like 5 minutes. It was much more expensive, of course. The reason I didn’t continue with Nood is because of the pain. I’d rather do 5 minutes of moderate pain than 30+ minutes of mild to moderate pain (knowing I’d have to do many more sessions). If that info doesn’t matter to you, this could be a great product.
