I love this product! I have light skin and coarse dark hair and I’ve noticed a huge difference after about the 3rd or 4th use. A lot of hair had disappeared and thinned out. I used it on a weekly basis, until I saw a difference. The only reason I give it 4 out of 5 stars is because it’s a bit slow. Seems like I have to wait 4-5 seconds to press it again to get a powerful zap! Other than that, no complaints, wonderful product!!
