I have been using HiSmile for 3 days so far and have noticed a significant difference in the appearance of my teeth. I have no hesitation in recommending this product.

First time my partner and I have used hi smile and we both love it!

I definitely see improvement, but not white.

I have noticed results, however I feel as if the gel does go quite quickly and i would go through the 3 included pens in like a week! So it could become quite a cost. However I have noticed some results on my front teeth mainly.

Love it! Very happy with the results thus far.

Received my teeth whiting gel this afternoon, absolutely love it ! Have been using it for nearly a year now and can’t fault it ! Absolutely love it Thank you !

The most amazing results After first using the pen it instantly whitened my teeth, though they were already white they’ve gone another 4 shades whiter from only a weeks use! So worth it for only $30 bucks

At first I wasn’t sure to get it because is a lot of products out there that don’t work. but I check the reviews and I say well let’s give it a try and after 3 days of use I have great results . This product works 100% I recommend to anyone .

I purchased the Ultimate bundle which included the Teeth Whitening Kit, Teeth Whitening Pen and Coconut Whitening Mouthwash. I have found results both the pen and the kit however the mouthwash was disgusting. I couldn't get it out of the tube and chunky texture was extremely off putting. However, the delivery was quick and couldn't fault the service.

I find the product easy to use and very good presentation but i did not see much of a difference. One other thing is that according to the sheet that comes to compare the color... I was already level 2... so i personally did not change at all...

I defiently noticed a whiter shade in my teeth. I have tried many different whiteners and this one defiently beat out the other ones for short term performance. Also, there was no teeth sensitivity after use. Having said that, I expected my teeth to get whiter than they did. The gel is expensive and you only get 3 syringes that run out fairly quick. It was a good time that was expensive and didn't live up to the hype.

Delivered in good timing. Fair price. Good customer service as I received an email from someone shortly after receiving the products offering help where needed. I have not seen much difference in the colour of my teeth and I am not sure if I am just imagining the change. I have followed all instructions, used the day/night toothpaste, and even drank my coffee through a straw to maximise the effects but I haven't seen much after spending £50 on products.

I liked using but the one thing that could be a but better was that I didn't know that you had the unscrew the top for the syringe so one of mine broke and spilled but that's my only complaint. Thank you HiSmile!

A great experience thanks you!

Im always skeptical about buying products online. I dont expect much but HiSmile is one of those company that actually shows good results. I highly recommend.

Hello, we used it the last week and we did not fell any results, we do not the problem. can you give ys any solution? thank you

The HiSmile system is so easy to use, and IT WORKS. Delivered very promptly and the instructions were a snap to follow.

Unfortunately this product did not work for my teeth which I was aware it may not work when I bought it.. I was worried I would not be able to get my money back but through the amazing customer service person I emailed. I got the most amazing service and got a refund for this product. I think this product is an amazing test to see if it works for you and if it doesn’t they’re so kind as to help out and refund you. I definitely recommend trying this product to see if it works for you!

it did lighten my teeth one or two shades, also lasted more than a month so far for two tubes of toothpaste. it does work

It was great just cant wait to get my refill gel pack!!!:)
