PL-58-100 Swidnica colgatepalmolive.com Review: Buy - 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 Review: Works a little after many applications. - 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. ## Features - WHITENS WHILE YOU SLEEP: Wake up to a brighter smile with Colgate Max White Overnight Teeth Whitening Serum, designed to reverse up to 15 years of stains* caused by food and drinks while you sleep. - PRECISION APPLICATOR FOR EASY USE: The improved precision brush helps apply the whitening serum exactly where needed.

You should dry your teeth first before applying the serum to make sure it sticks to your teeth for great results. **Q: How many applications does the Whitening Serum have?** A: Each Max White Overnight Serum contains 35 nightly treatments, when used as directed. **Q: How much serum should I use per tooth?** A: One dip of serum is enough for approx. 5 teeth, ensuring even coverage and optimal whitening. Do not over apply the product. Excessive use may result in a hard film forming on teeth. If this happens, remove it by brushing your teeth more thoroughly. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Buy *by A***S on 11 July 2026* I swear by this!
