Review (5/5): Seems to actually work so far!
I read most of the reviews said that it really works, so that's what convinced me to purchase it and I did! Honestly I thought that it would take foreverrrr before seeing any results, but honestly I started noticing a difference after just a couple of uses. Though it's not going to instantly go to bright white even after a few uses, it's more like a natural progression to a whiter color if that makes sense.
Side note : not sure if it's just me or what, but I feel like I've reached a point where even after days, it seems like my teeth aren't getting any whiter / it's not having the same affect. I also think that it just might be me not being able to personally see the difference, since like I said it can be a bit of a gradual buildup for a whiter color.
