I used this on a strict regiment and went past 16 weeks on my underarms, pubic area, lip, and legs. For reference, I have fair skin and medium thick hair that is black/dark brown. I don’t shave my legs. I’ve used laser hair removal and had great success from that. But when I used Nood I didn’t see results in any area I was using it on. I was able to return it for full price. Attached is a picture of my legs two months after completing the Nood process.
