Instantlywhite レビュー 

Over the moon with this product as it does exactly what it says on the tin and quick delivery time too

Was hesitant to buy after trying loads of other home teeth whitening products that failed to work but this actually works. My teeth feel so clean and my gums have stopped bleeding after 1 week of using their powder and my teeth are a few shades whiter already. Will definitely be buying another tub when I run out

Didn't do anything for my teeth. Used as instructed (if not more times) for 2 weeks and it's made no difference. According to their IG/website you should see a difference in 2 min and my teeth should be 8 shades whiter by now--lies! They also advertised money back guarantee, which is why I decided to give it a try. When I emailed them, no response. Then contacted them through FB, and apparently it was the director of the company that finally responded and said the money back guarantee was a mistake. Well that's false advertising, and refused to refund my money and stopped responding to messages. Now in touch with my credit card company to dispute the charge.

They also use IG "models" who have had their teeth bleached. One of the models has even posted it on their own account. So they're using models with bleached teeth to advertise a product that does not give an appearance you see.

Avoid! Oh, and if you post on their IG that the product doesn't work, well they delete the comment and block you.
