  • Use with LED light tray to maximize results.
Color: 4 Syringes Gold
This worked extremely well my second use my teeth were super white. Tip use with a led light tray, you will see better results than you would see with a regular tray.

  • Works better than strips and other gels I’ve tried.
Color: 4 Syringes Gold
Works better than strips in a much shorter time. Strips just didn’t seem to do enough after several wearing, but I saw a difference with this product after one 30 minute use. I do not have teeth sensitivity, but if you haven’t used a whitening gel, you might want to try a lower percent first.

  • Good but you better have pain tolerance
Color: 4 Syringes Gold
Works well but man it’s potent and painful if it gets on your gumline. I’m dropping back down to 35% peroxide.

They aren't messing around with the 45% stuff!!! Don't let it eat your gums!!!! Make sure you only put tiny dabs in your trays or this stuff is like a prisoner torture.
