I tried the teeth whitening device the Kardashians swear by, so did it live up to the hype?

Hi Smile Teeth Whitening Kit, £49.99

THE HYPE

Some people swear by swilling coconut oil for whiter teeth or use activated charcoal and a whitening kit in an attempt to remove stains. But the Kardashians’ go-to teeth whitening device? The Hi Smile Teeth Whitening Kit.

Confession: I am a marketing person’s dream. Despite being cynical enough to realise that the Kardashians were being paid to promote the Hi Smile Teeth Whitening Kit on their Instagram accounts, I wanted in.

After pouring over pictures of Kylie Jenner and Kourtney Kardashian working on their Hollywood smiles with this curious little device, I was set on getting my hands on one.

In the £49.99 product’s description, the makers say their kit has been designed to deliver maximum results in 6 applications, with each application being only 10 minutes. “Our key ingredients ensure there’s no pain or sensitivity caused throughout the process while delivering results of up to 8 shades whiter teeth,” they claim.

The company’s tag line promises: “10 Minutes. 3 Steps. 6 Days.” But can you really achieve a set of pearly whites in under a week? I was about to find out.

I drink too much coffee and too much red wine but because I have a penchant for whitening toothpastes (and am even partial to a spot of oil pulling), my teeth aren’t too discoloured. While I don’t want to emulate Jack from Love Island’s blindingly white gnashers, taking my smile a few shades lighter is the goal.

THE REVIEW

Firstly, I love the kit. It’s neat, straightforward and compact. Inside the box I found the LED light (a gum shield-esque device attached to an LED light), three syringes full of the whitening gel, a day toothpaste, a night toothpaste and a set of concise instructions. First impressions? I’m getting a lot of bang for my buck here.

I found the instructions a little confusing. They instruct you to apply ‘a quarter of the syringe to the top of the tray and also to the bottom’. On first application, I missed the point and used just one quarter for both top and bottom, rather than a quarter of the gel on the top and then another quarter on the bottom. Maths was never my strong point, OK?

I inserted the tray into my mouth whilst watching Netflix and the 10 minutes flew by. I have super sensitive teeth and didn’t feel a thing. After use, you simply wash out the tray and your mouth with water and head off to the land of nod. It really couldn’t be much easier.

There’s also the day and night toothpastes, which you’re supposed to use twice a day. The Day Toothpaste is designed to protect your teeth from stains during the day, with micro shield wax forming a protective barrier over your teeth. The Night Toothpaste, which has a black hue thanks to the activated charcoal ingredients, is designed to naturally remove stains and help whiten your teeth while you sleep. I wasn’t totally sold on the toothpastes and followed up with my regular choice for a fresher finish.

THE VERDICT

I didn’t notice my teeth getting whiter by the day but after the six sessions, they’d definitely lightened by a few shades and I particularly noticed they were brighter in photos. Whilst I didn’t receive any comments about their lighter hue (unlike when I tried whitening my teeth with oil pulling), I was pretty impressed with the results. I’d be tempted to buy another pack and give it another go but a trip to the dentist for a professional teeth whitening session could work out much more cost effective. Thanks to this nifty little device, we really can Keep Up With The Kardashians.
