I've now used my nood 5 times (set my calendar for every 2 weeks from the first time I used it, so 10 weeks or so) and while I've noticed that the hair in my pit and on my lip are definitely lighter and thinner, they haven't stopped showing up. The hair on my chin....well....it's stubborn apparently. I'm not giving up yet, I'm hoping the more I use it I'll start to see less and less, but as of right now, well, I'm not super impressed. I'm happy to update if things get better.
