The peroxide free teeth whitening kit worked a treat! I noticed an amazing difference after only my 3rd application and have been using HiSmile daily. My absolute biggest love for HiSmile is because of the fact that I have experienced no pain or sensitivity issues at all. I've had a smile on my face for the past few weeks and am so happy with my purchase, will definitely continue using HiSmile!
Bottom Line: Yes, I would recommend this to a friend
