Pros and cons
Pros
- After-brushing step can be added to a routine without replacing toothpaste.
- The listing identifies the immediate effect as temporary and distinguishes it from stain removal with continued use.
- Contains no peroxide according to the listed material-free claim.
Cons
- The whitening effect is described as temporary, so it is not a permanent colour change.
- The listing says the serum lacks fluoride, so it does not replace fluoride toothpaste for routine oral care.

What to know before buying
Listing details to confirm
Use after brushing with fluoride toothpaste, not instead of it. Directions say to brush with Colgate Max White Ultra toothpaste, apply one pump of serum, brush for two minutes and rinse. The listing warns that temporary sensitivity may occur, says to keep it out of reach of children and not to ingest it. It also says staining foods and drinks may shorten the visible effect.

Customer feedback highlights the serum's colour and taste positively, but reports on effectiveness and value are mixed. Some say it works well, while others report no effect. Experiences with how long the visible effect lasts also vary, from lasting a while to only minutes. This matters because the listing itself describes the immediate colour correction as temporary, distinct from surface-stain removal with continued use.
Positive themes
- Customers like the product's colour and taste.
Mixed feedback
- Feedback on effectiveness and value ranges from favourable results to reports of no effect and poor value.
- Customers differ on duration, with some saying the effect lasts a while and others saying it lasts only minutes.
