When I first got an email about this toothpaste I was really intrigued. Toothpaste with an LED light? How does that work? Well I got my answer!
Blanx White Shock contains Actilux which is activated by UV light so when you remove the lid it the light switches on and activates the Actilux, thus whitening your teeth. You can also use the light on your teeth directly to whiten them further. The theory is that Actilux also reacts to sunlight so every time your teeth see sunlight it whitens them more...an excuse to smile?
The light and toothpaste come seperately so you can is reuse the light once your toothpaste is finished. I have to say I do think the light is a little bit of a gimmick and the amount of time that the product would be exposed to the light in an average use is fairly minimal so likely to be ineffective. I can't say I've noticed a massive difference in the colour of my teeth but it is a nice toothpaste and leaves your teeth/mouth feeling really clean and fresh.
Upon spotting this in the bathroom, boyfriend was like "ooh, this is a fancy toothpaste!" and when I explained about the Actilux I got: "Hmm, sounds like a gimmick..." - which to be honest would sum up my review in a sentence.
As with all whitening toothpastes, this isn't going to make your teeth Cowell-white in the space of a day. I do think the only way to get really white teeth is to get them done at the dentist (or Crest Whitestrips are pretty good too though again it's fairly subtle!). I'm not sure that I'd buy this again, though it is a decent enough toothpaste, I don't think it really gives the kind of whitening results that I want.
This costs £6.99 for the toothpaste and LED light with further tubes of toothpaste £4.99, available from your usual toothpaste stockists.
