Liquid Smile Professional Whitening Pen - Lemon Lime 2 g.

I have been using this product for several years. The only whitening pen that I can see immediate result after just one application. The only disappointment is this product is very expensive and doesn't last very long. I drink coffee every day an need a whitening pen to keep teeth white. I wish it were more affordable.

Same item I purchased at my dentist office previously at triple the price, shipped fast and love the pen works really good on teeth and stains

Not worth the COST...

I liked this product it works great. I have sensitive teeth the product did not bother my sensitivity at all. Whitened my teeth two shades lighter.

My wife ordered this product and received a defective product in that the "pen" container does not dispense the product. When we tried to return the product the seller said "no returns no refunds". I will update after contacting Amazon directly as this type of thief should not be allowed to operate on this website! Beware of seller PMG2010 with a store front of www.amazon.com/shops/A243BVFOT2MK4D. You've been warned!

I think Crets white strips are much better.

This did not whiten my teeth at all. Not even one shade lighter. The liquid is too runny and it doesn't stay on my teeth. As soon as I close my mouth I can feel/taste it running off my teeth and I end up swallowing it. But hey, if you can keep your mouth wide open with your lips curled up for EIGHT hours every night and not swallow at all during that time then by all means, give this stuff a try. But I promise you it won't do anything it claims to do. I feel really ripped off. I bought it at a cosmetic surgeon's office and I'm surprised that an actual doctor would sell something like this. I am going to speak to him about it at my next appointment (I see him for a skin issue I have and saw this in his office and bought it. I thought "HEY! If a good doctor like him sells it then it MUST be true! Pffff! WRONG! I wonder if he feels ripped off too, having a shelf full of this useless garbage) I wish I had just put the money towards a professional whitening treatment at a dentist's office instead of buying into the hype of Liquid Smile. Because that's all it is, a pretty package and hype from a great marketing department. Go ahead and buy it but you have been warned. It won't work. It literally does NOTHING.
