At least 30mins

Thr guideline is 15minutes, however it doesn't work. I recommend at least 30minutes! You will see the difference but I feel like I've wasted 1.5 of the gel by only leaving it on for 15mins.

No Difference

Have been using this for a few weeks and haven’t seen any difference at all.


I use this every two weeks to keep my smile white. I've had no sensitivities or discomfort whatsoever.


Only a minimal amount is required. It works quickly for each application. To use this product, I recommend getting trays.


This refill gels are great because I have sensitive teeth. I signed up for subscription monthly for top up
