HiSmile Teeth Whitening Kit

Works well.

Hasn't changed the shade of my teeth even though used it everyday

Didn't change at all

I was sceptical too it as always with these kinds of commercialized products, but its easy to use and has a simple step-to-step guide. Clean package and everything; already seeing results after 4 uses.

Crap didn’t work gel lasted one week. Waste of money.

I will never use any of hismile products again. The product does not work NEARLY as good as it is said to do so. The kit does make a slight difference, but it's barely noticeable. Not to mention the ''one fits all'' mouth tray that does not cover every single tooth equally at all. One fits all is just a wrong approach when it comes to teeth, it's like saying one the same shoe will fit everyone. The brand has made a lot of effort to promote their whitening kit via youtubers and other influencers paying/sending them free products with specific guidelines on what they're allowed to say - which leads people to think great things about it but it does not make it true. I am someone who already has their teeth in quite good condition (straight and not the whitest but definitely more white than any shade of yellow). I assume the product MIGHT WORK well for someone whose teeth is very stained/in poor condition and make a big difference, however, once your teeth is quite white already and you want it to make it even whiter this product is not going to do it for you. So far, the best whitening product I have used is whitening strips from Crest.

I have ordered the kit, the refill and the night and day toothpaste. I was not expecting my teeth to go to a perfect white straight away. I saw a slight difference after first run and was hoping to go to a nicer white the second time. But there was no difference at all even after using the day and night toothpaste everyday results never came up. My teeth are back to way they were after £70 out of pocket. Would not recommend at all.

I've used this for one night so far. The mouth guard is one-size fits all and didn't cover all my teeth equally, so quite a bit of the gel got into my mouth. I now have ulcers/chemical burns at the very bottom of my gums, and it hurts. Bonjella helps but now I'm not sure I should carry on, I don't want to damage my teeth or mouth. I think my teeth perhaps look a little bit whiter after the first use, but I'm not sure. Will write another review in 5 days.
