Review (5/5): Noticeable whiteness with little to no sensitivity!
I've seen this product quickly get sold out on Sephora's website. It was on sale on Prime day so I thought I'd give it a go at such a great price. I have professional whiting kits from my dentist that work great but I my teeth are more prone to sensitivity. This minimally increased sensitivity with great results! The taste of the whiting gel isn't the tastiest but finding one you enjoy the taste of is a fool's errand. Even at full price, it's worth the cost. I even got an extra mouth piece for my significant other!
