I had been seeing a lot of light pulse therapy on my Instagram, but Nood was the only one that was FDA approved. I figured I had nothing to lose with the three month trial. I’ve used it on myself and my husbands back, and I have definitely been impressed with the results. I’ve used it on my legs, bikini area, and under arms. The best results are on my legs where I have been able to tolerate level 6. I have used level 3-4 in the bikini area, and I do get some pustules there after therapy. I think using antibacterial soap is key. Also noted pustules to my underarms after therapy. But honestly if I don’t have a 5 o’clock shadow permanently in my underarm area, I can get over the transient pustules. I would recommend the company clarify how my times you go over an area better in the papers. Only one paper says I should be doing it 3 times for a session, which was confusing and not what I had read elsewhere. I do love the ability to be able to watch TV and remove body hair at my own ease!
