Face LondonTeeth Whitening Refill Kit 2X 5ml Gel Syringes with Up to 8 Shades & Zero Sensitivity Teeth Whitener Refill for Stain Removal | Teeth Whitening Gel | Teeth Stain Remover

You need the other kit to pull this together as a practical teeth whitener, but this is good stuff - recommend.

These teeth whitening kits come with 2x 5ml syringes, and are packaged fine. The product itself when applied didn't have a foul taste unlike some whitening kits I've used in the past, which was a bonus. I did indeed notice a quick improvement to the colour of my teeth, but when comparing photos, it seems very short-lived and seemed to darken back down within a couple of hours. It seems like the product might not be truely effective.

We were a little hasty in ordering this teeth whitening kit from Face London. It does state specifically in the product description that this does need to be used in conjunction with an existing LED light kit, however we did not note this, and therefore were a bit stumped when it first arrived.Once we had obtained a light kit, we were happy with the product and how it is to be used. We like that it contains ingredients which help sensitive teeth - we both suffer from this, so it was a relief that it was sensitive teeth-friendly.We are well aware that teeth-whitening processes at the dentist can be very expensive, therefore home treatments are a more wallet-friendly option. As is often the case with home remedies though, there is going to be some notable differences in performance in comparison to the pro options.So while this kit does make a difference, this is a product that is to be used on a number of occasions, rather than as a one-off treatment. If you have the home set-up ready to go (LED light kit), then these refills are decent value for money and can offer an effective way of bringing out the whiteness of your teeth. But be prepared to do this over a period of time.

Cleans and freshens your mouth but doesn’t really do the whitening it promises.

I bought this Face London Teeth Whitening gel to try as the price was good and it does help a little bit to whiten the teeth and the product does not last very long. I would buy it again though.

I love that this is available as a refill kit as I have several lights and trays already. The syringes allow for very precise application without wastage. I can definitely see a difference and will buy again.

Easy to use, tastes OK, reasonably priced. I would dispute the whitening capability though.
