Damn, I just love this product. Being a waxing person, I had never thought of switching to any other method, but after seeing my best friend using it, I couldn’t stop myself from buying one. And I am glad that I purchased it as it swiftly removes the hair without providing any damage, burning issue, or infection. But yes, the laser device will not remove all the hair in the first use!! If you are going to use it, then you need to be really very patient. Since I have used it, I can guarantee you that within 5-6 weeks, you will completely get rid of all the hair. So, just have patience and use it without any hesitation.
