I purchased this laser a bit skeptically, because i only had the one review to go on, however im SOOOOOOOOOOOOOOO glad i did!! I had laser done about 5 years ago, i only just started taking skin supplement tablets and then found after a few weeks to my horror that my facial hair had started to grow back! I couldnt go back to the salon to get the laser done because its so pricey so thought itd be safer to invest in one that i could use at home anytime i wanted. I use this once a week and have been doing for the past 4 weeks and i must say i can definately see a diffference!! i dont have to remove hair as often, infact i dont need to at all on my face. As for other body parts it doesnt seem to work as well on the finer hair, although i just bleach these and bobs ur uncle! The only reason ive given this a 4 star is because you have to replace the cartridge after about 1000 pulses, you'd think that was a lot, but somehow its not! If your thinking about purchasing a laser, id say definately buy this one becasue u can use it on your face (with many others you cant) and mainly because it works! but remember, only works on light skin and dark hair!
