I've only used this product once and there is a significant difference in the colour of my teeth! Super easy to use and results are quick. I will definitely keep using

I just used this whiting pen, I'm amazed by the results. You can see a considerable difference from one use. I paint each one of my teeth kept my month open for about 30 seconds to a minute then closed my mouth for a minute and opened my mouth. I couldn't believe how much whiter they are!! Very impressed!!

This teeth whitening pen is excellent! I have tried other teeth whitening pens over the years and this one is, by far, the best one I've used.

I have been wanting to order one of these again I absolutely loved it I think it does what it says it's going to do and I only used it once a day after I brush my teeth. If you drink a lot of soda or coffee you're going to want to do it twice a day and if your teeth are really damaged then you need to see a dentist and not expect a miracle.Just saying.

I bought this a month ago and only use it once a day and it has made a big difference for the good!

Wouldn't have ever wasted so much money on two gels pens yes I bought 2 thinkin another one would matter I use it with my led go smile and clearly doesn't work

I bought this over priced product thinking it would be a good gel pen to use with my go smile led teeth whitening I won't ever spend that kind of money on something again before asking for a free trial!!!!

A friend recommended this product to myself. I am going to get

Picked this up before my wedding - I don't go in on the pure-white-bleached-enamel trend (and have sensitive teeth) but I also drink a lot of coffee and have one darker tooth. This doesn't (as is the case with most products) change the color of your underlying enamel, which is some color of ivory (not white). It DOES clearly reduce surface stains that accumulate from coffee etc. The brush application meant I could apply it to my darker tooth extra and offset the contrast. Happy with how it came out for my wedding. My biggest concern was I once tried the crest strips etc back when beauty standards were getting more in my head and had HORRIBLE sensitivity, so I was worried about trying this, but no pain and no gross peroxide aftertaste. Stays minty and sweet. Wish directions were on the tube and more clear about how long to let dry (60 seconds) and that you're supposed to leave it on.

Spent a good chunk of the morning rotating the bottom of the pen but the gel won't come out onto the brush. Doesn't matter if the triangles line up, the brush is conpletely dry.
