I've noticed a slight improvement in whiteness since using the product but a routine dental hygienist appointment yesterday afternoon definitely accelerated the process.
I'll continue to monitor progress but still remain undecided regarding products sold on Facebook.

Excellent product, noticed gradual improvement after 2 days. Of course others are different depends on coffee intake and dark fruit will also satin teeth. On week 2 and more noticeable

Firstly, I appreciate the appropriate timing to request a review!
I rarely give reviews.
This product is worthy.
I've seen good improvement in the whitening effect on my teeth. I've not experienced any sensitivity. I've used dentist moulds and branded whitening gel, where the mould left a gap on my bottom teeth ( apparently to not have the gel touch my gums) however that left a very dark brown stain there. This product has impressively reduced this stain.
I will purchase again.

Only been using for a few days but I already see a change, and hopefully I’ll continue to use and make my teeth brighter.

My teeth are probably 2 shades lighter. Your teeth feel very clean
