I use this before using the whitening accelerator and toothepaste as instructed for best results. I am not sure it has an huge impact on the results but I see a small difference so I will continue to use it. 

I first tried this in the six minutes to a whiter smile boxed set from SuperSmile, which I liked so much I ended up buying the full size of all the included products! I see immediate results when I use the SuperSmile system so much so that I’ve recommended it to friends leading up to their weddings and other big events. Don’t hesitate, just buy it!

I use this before the accelerator and toothpaste. It seems to work better using all three products.

I have been using this product for a few weeks and I think I do notice a difference. My teeth seem a bit whiter so hopefully it will continue to work better over time.

I use this with the toothpastes as a system. It's the only effective whitening brand I've been able to use without irritating my teeth and gums.

Whitening pre-rinse works well along with the other Supersmile products. It has a mild taste and is definitely to be used before brushing.

I do believe this has aided in lightening my teeth. However, the taste isnt refreshing but lucky it goes away shortly after you start brushing your teeth.

Really, I did not see any difference and I consistently used the product until it was totally gone.

I love this morning and evening before brushing. Beside being a pre clean, it is so fresh and makes my routine complete.

I've only been using the Pre-Rinse but it works so well just by itself, it just takes longer. I took a selfie a couple of days ago and thought wow! my teeth are so white. The other great thing about it other than the fact that it works, is that there has been no sensitivity at all. I try to use it morning and night but not always, it's so easy to add to your daily routine. Definitely buying again and will probably try the 6 Minutes To A Whiter Smile kit next.
