I’ve been trying to find a teeth whitener that doesn’t require you to smile big for 2+ minutes while the product does its job - it feels like a super long time every time. The HiSmile Color Correcting Foam is unique (it’s purple and it being a foam) and I actually look forward to whitening because you only need to swish it around for 15 seconds and you’re done. I’ve also just started using their pap+ toothpaste and really like the precise tip on it.
Currently everything ships from Australia which took a while to get to me in the US. It would be great if they expanded!
