The High Smile Purple Serum has garnered attention for its potential to whiten teeth. Utilizing a unique formula, this serum is an alternative to more traditional whitening techniques.

Users of the High Smile serum, as observed through before-and-after photos, notice some level of brightness in their smile. A user described how around day six, a noticeable whitening effect took place.

Yet, these effects are described by users as "minor improvements." It appears that while the serum can produce results, the changes are not as pronounced as other whitening products in the same category.

For those seeking deeper teeth whitening, the mentioned alternatives might provide a more satisfying experience, at least for shorter results.

One of the main drawbacks of the High Smile serum cited by users is the requirement to use the product post-brushing. The fact that it acts as a serum rather than a whitening toothpaste means that it must be incorporated as an extra step in one's daily regimen.

• Added oral care time investment
• Serum application post-brushing
• Plaque control and aftercare steps needed

Some users report that maintaining this additional task - particularly when pressed for time - is a significant inconvenience. Feelings about continuing indefinitely vary. While some decide to incorporate this extra two-minute step into their morning routine, others lean towards using quicker methods when attempting to reduce discoloration.

It's doable but I wasn't the biggest fan.
