Professional Advanced Teeth Whitening Pen - Up to 8 Shades Whiter - 100% Safe for Enamel - Vegan - for Sensitive Teeth - Rapid Results - Clinically Proven

After trying several other whitening products over the years I was sceptical about using this product.Within 2 days of using the product I noticed results on my teeth, my smile looks brighter. The gel is really easy to apply and works in just 10 minutes.I am amazed at how quickly this product shows noticible results and I've had a couple of people ask me if I've had my teeth professionally whitened 😁.10/10 for this product I will definitely be buying more when this one runs out!

I purchased this after reading a positive review in a Sunday paper. What the review did not say was that there is only 2.5ml in the pen which - as the company have now told me - is only enough for 5 - 7 uses! I used it twice a day per the instructions on the pack for 2 days and then it ran out so have no idea if it would have worked if used for longer. Definitely not a good buy.

I have not long had this product so I am unable to give a final review. The product was delivered quickly and tried it straight away, it's very easy to apply to teeth with no lingering aftertaste. After a couple of applications I can see a slight improvement in colour but need to use the product fully before I can properly evaluate.

I had high hopes for this product, however after using it as per direction, twice a day, brushing in the gel on the teeth and all, I see no difference at all, and what’s worse, I can see some gel left through the transparent bit of the pen but no matter how much I turn the bottom it doesn’t come out anymore.I have a feeling that there’s way more gel in the pen still but because you cannot see, you would never know..Won’t be buying this again. Off to look for something else

Have not seen or used a product like this before. The application process took a little getting used to but once applied a few times it was pretty simple to get used to. No sensitivity at all unlike many other products and can see a difference after applying for 7 days.

I have been using this whitening pen daily for a week now and I have been really impressed with the results. As a smoker, I was not expecting to see much of a difference but I have definitely seen my teeth look much cleaner which was exactly what I was looking for without having to go visit the dentist. Really happy with this whitening pen from smile science, definitely a great value buy which I would recommend to anyone looking for cleaner teeth!

Bought these pens from supermarkets and now I have purchased 3 from Amazon , the last one ordered on 11/3 has just been opened and it doesn’t work , I can’t be bothered with the faff of returning it any chance that it can be replaced .update sent this back for refund and living in hope that it would be a one off I reordered 3 and guess what 2 don’t work so they are being returned, short dated stock also. DO NOT BUY THESE

It does improve the colour of your teeth but i didn't think it was value for money for one but I bought from the same company and got 3 of them for less than a tenner and it's really has improved the colour of my teeth would recommend buy multi pack
