After just 3 nights using it, i can see a very subtle difference so I am already very happy. I used to smoke for 20 years then switched to vaping, so my teeth were unfortunately a bit yellow. I'm glad i bought this so I can have the confidence to smile more. If I can see a difference after 3 days then I look forward to how it looks after 30. You have to make sure you dry your teeth after brushing, then apply the serum, then make sure it dries. Don't put too much on because it'll get onto your gums and can irritate them.

Takes a lot of separate applications to make a little difference. I did a comparison by doing just my top set of teeth only so could do a direct comparison with the bottom, untreated set of teeth - to see if it actually works. Yes, but very subtle, but then again, the advert pic - before and after - is not a dramatic difference anyway.: and that is the level of shade difference I saw on my teeth. Application wise - the gel is clear, so cannot see if missing bits when applying it - and also, will be difficult to see when it has actually run out, as cannot see if there is any on the brush - I am still using mine after a couple of weeks and it could be that there is nothing left and i am just using the brush against my teeth with nothing on it! So will just have to decide on a day to stop, Would be better if the gel was coloured, as you are using it overnight in bed, so would not really be an issue with a coloured gel.

I've been using this for 3 months now, over time I would say it has lifted my teeth 4 shades,you have to.be persistent and use it every night. Its not an overnight fix.my teeth were always white due to the menopause they discoloured slightly. I think this product its the best I've tried .

I swear by this! No taste to it, I use it with the LED light and you can really see a difference in colour after use, dries down quickly works so well

Absolutely useless waste of money, just leaves chunks of white stuff on your teeth that didn’t come off with using an electric toothbrush I had to scrape it off, don’t bother wasting your time or money on it

The seller was great and quickly sent a replacement when my first pen never arrived, so I really appreciate their service. Unfortunately, the product itself was a big letdown. The pen goes on like some kind of dental glue and leaves a sticky layer on your teeth. I tried it a few times, but honestly, I couldn’t deal with the sensation - it felt gross and made it impossible to relax. I gave up before seeing any results, so I genuinely have no idea if it whitens or not. Let’s just say… you definitely need to be single or sleeping alone to use this without embarrassment 😅 (which I am - and still couldn’t tolerate it).

Spot on

For someone who has tryed so many thing's to get their teeth back to the normal colour (without smoking, lot of coffee at point's) over the years my poor old teeth took alot and was quite embarrassed as alot of people would be, eventually after so many things brought I got this peace of kit AND Wow what this product has done to my teeth in I think we worked it out to be the 6th day and 50%of my front top and bottom were getting back to there colour again, as we all know we can never achieve our true colour back, but this has impressed me so much and who ever say's it doesn't work are obviously not doing something right, it's so simple!! YOU'D BE GLAD YOU TRYED IT😁, do not get near gum's as it will burn, top product would recommend great value for it's money💵👌😁😊

It is not working
