I use the No-No on my face. It's great for the peach fuzz, which was quite heavy for me. I find that it does grow back, but is not more course or thick than before. I use it every other week or so (probably should use it every week). There are a few course hairs that I've been plucking for years. The No-No does work on these, but it's not as effective as the tweezers. Be prepared for the smell of burning hair. That's what it does - burns the hair. It doesn't hurt and doesn't leave my face red or irritated. I've been insecure about my facial fuzz for years - the No-No is definitely worth it for me.
