Have to be more faithful to the process than I have been, but saw results when I used it.I have so far only done one treatment and there was definitely serious whitening. The flavor is mild. It’s easy to use.This product works great and quickly. Also does not hurt my very sensitive teeth at all!Product is easy to use and works as advertisedI LOVE this product. I was a little skeptical because I haven’t had success before with other teeth whitening products/strips. With iLumi, you can get results much faster than typical teeth whiteners so I thought I would give it a try and I’m so glad I did!I have a small mouth so applying the gel wasn’t the easiest, but once it’s on you just pop in the light and let it sit. So so easy & you will see results fast. I wish I had taken before photos to share, but bottom line - I love this product and totally recommend it!!I LOVE this product. After only a couple uses my teeth were so much brighter, and I have received so many compliments. My teeth are normally super sensitive to any whitening gels I’ve used in the past, but the iLumi gel must be magic because I will rinse or even drink cold water after uses and my teeth feel perfectly fine. Also super easy instructions with diagrams on how to use!I was a little reluctant to try this as there are so many empty promises made by companies of all sorts. I’m actually glad I went ahead and tried it. It really works. If you’re on the fence, go ahead and buy it. You won’t be disappointed!This product is so easy to use. I’ve used other teeth whitening products before and they’ve either hurt my teeth or are sticky and annoying to use! This is so so simple and I can already see a difference after just a few uses! It doesn’t hurt my teeth at all and it’s a simple clean up. Also easy to bring with me when I’m traveling! Comes with two settings. Also, the packing is great! 10/10 would recommend!
