I purchased the V34 colour correcting serum…….BOGOF offer so £19 for 2 bottles, email confirmation, updates on my order, delivered on time so faultless there. However, it’s so not what the adverts pimp the product to be. Fortunately my teeth are in pretty good condition but my wife wanted to give it a go……over a week and literally no difference, IF there is a difference you wouldn’t notice. The adverts have instant Pearly white teeth, you have reviews all over Google with people saying ‘just after one use my teeth were white’ there are even people saying it on here 🤣 it’s just not true, it may work to a minimal extent but nothing like the BS you’ll see from advertising and what I can only assume are paid reviewers. I’m not saying it’s a scam but it’s very falsely advertised which shouldn’t really be allowed – – will it work after one go…….NO- will you have pearly white teeth instantly …..NO- is it worth trying…….it’s not expensive so if you really want to- are the adverts true – NOOOOO!!!- will people notice……NOSeriously it’ll barely do anything I’m just being honest and if you want white teeth I’m sure there are much better products out there. This is just a product of the power of social media……and somebody is very rich because of it. That’s just the way it is
