Colgate Max White Overnight Teeth Whitening Serum - Home Teeth Whitening Pen - Reverses 15 Years of Stains* While You Sleep - New and Improved Applicator - Enamel-Safe - Easy to Use

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 gun's as it will burn, top product would recommend great value for it's money💵👌😁😊

Unfortunately didn't work well for me. I'd say value for money and size would be good if it worked but the quality of the product seemed very cheap and didn't work. It turned all stringy and didn't stick to my teeth well, not sure if that's because I applied it wrong but me and my partner tried multiple ways and it didn't work. Seemed easy to use and looked nice, but wouldn't rebuy. I'd imagine the whitening effect would be good with me using the colgate toothpaste with the same design. Size seems reasonable for the price.

Does whiten teeth with regular consistent usage but after you stop using it the teeth do darken a little pretty much straight away but not as dark as start. Went to an a2 colour but couldn’t really get it lighter with this.

A complete waste of moneyDoesn't do what it stated it would do.Leaves your teeth patchy and comes off as soon as you brush your teeth or eat

Amazing product good value for money

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).

After only 3 day! You can clearly see the difference! I use it with the matching toothpaste.

not effective
