Noticed a difference after 2 days. By the end of my 14 day pack, my teeth were shiny and much whiter. Even my sceptical husband noticed the difference.

They work! That’s the main thing, since I last used I like that they leave less taste but the adhesion has changed - really difficult to get off or come off in pieces & leave a residue.

Visibly whiter teeth

Very impressed with the results I’ve seen from gleam, I’m 10 days in to using the strips and my teeth and visibly whiter not just to myself but to others too which I am very happy about. Easy to use and I would highly recommend to anyone thinking about buying.

Easy to use and comfortable

The strips are very easy to use and come with a really helpful whitening guide to use against your teeth to see progress. The strips are comfortable and easy to keep on for the full 30 mins. They do leave some residue but it is clear, easily wiped off and you can brush away excess. I havent had any sensitivity while using the strips. I have used the full 14 days, have seen a very slight improvement but nothing drastic like some advertisement videos. I do feel another pack will help to see more improvement and so will use the product again.

Better than other whitening strips I’ve tried

Really good product. I’d tried other strips recently but don’t find they made a difference. I was persuaded to try Gleam after I’d read a positive article about them in the Independent, and am really half I gave whitening strips another go. I’ve now used them for a week and definitely can see an improvement. I will stick with them but so far, very positive. Good delivery service too!

Make sure your teeth are dry as instructed, as they won't stick properly!
