The Lumineux® Bright² Teeth Whitening Pen

I have purchased this before.....I just started to use this specific pen because I was finishing another. Less than a week into this new pen apparently I have run out of whitener? Crazy, I have not used it more than 3 times. I would like a refund or at least another pen in case this was just a fluke. Kinda disappointing to say the least.

Unfortunately, the product made my teeth sensitive and did not whiten.

Probably need to give it some more time? I’ve only been using it for about a week.
