This truey is painless! It gets warm, sometimes hot, but it doesn't hurt. I have used other laser hair removers and they sting so I was excited to try this. It comes with attachments for the bikini area and skin spot lightening. I've used it on my face and haven't seen any difference, but only 2 times. My daughter's dark hair has seen results within a week. You can see the spots I left out on her ankles and feet because it's growing fast, and the smooth parts of her legs that I can easily hit with light have noticeably lighter hair growth. Functions are easily set with a simple dial, and the button is conveniently located to turn the light off. They provide goggles for safety and all you have to do is hold the button and the lights will automatically turn on as you slowly move the unit along your legs, face, etc. I will update as I use it and let you know how quickly I see results on my facial hair.
