MY TEETH are, frankly, the stuff of my dentist’s nightmares.
One minute, I was young and fun, smoking it in a nightclub, and the next, I’m deep, tragically into Earl Gray – the kind of habit that lets its cloudy elements smear all over your enamel.
It means my teeth are currently the color of slightly old Dijon mustard.
HeySmile teeth whitening stripsso it’s my last desperate attempt at a perfect set of white pearls before I board the plane to Turkey.
After all, life is short and I’m determined to smile while I still have teeth.
Read on for my full review HeySmile teeth whitening strips.
Advantages:
- Noticeable difference in whiteness, especially after continuous use
- I didn’t get the post-whitening toothache that I’ve experienced with other brands
- Free next day delivery for Amazon Prime members
- Relatively affordable compared to competitors like Hismile
Disadvantages:
- Difficult to apply
- Don’t expect results overnight
Rating: 7/10
Quickfire Q&A
How much is HeySmile? A pack of 28 strips — enough for 14 treatments — is £19.99. By comparison, Hismile, one of the biggest names in teeth whitening, sells the same number of strips for £29.
Who is it best for? Those who want to apply them regularly, to see their full results. Also, these aren’t the same as a trip to Turkey – they’re more for people trying to get rid of last week’s coffee stains.
What we loved: The biggest win was the lack of post-treatment throbbing, which I have experienced with other brands.
What we didn’t do: It is a bit difficult to implement.
The Nitty Gritty
First impressions

HeySmile Teeth Whitening Strips (28 Pack), £19.99 from Amazon
HeySmile teeth whitening strip app is a focus test.
It’s like trying to perfectly execute a sharp liquid cat-eye on the train to London — it requires absolute, unflinching precision.
You have one gooey piece for the top, another for the bottom, and immediately they try to fold in on themselves, vaguely tasting of mint and hydrogen peroxide.
For the required 30 minutes, you are strictly prohibited from talking, drinking or engaging in distracting activities.
It’s weird, but it’s worth it in the end.
Does it deliver?

Wearing the strips means enduring the light squeeze of sensitivity, which is just the hydrogen-powered whitening engine ready to burn off those years of stains — or maybe just the last two weeks of latte foam.
It’s uncomfortable, slightly uncomfortable and absolutely not relaxing. But then you peel them off, and that’s when you get your teeth back — sort of.
These stripes do not suddenly “whiten”. They offer a small upgrade.
You go from the shade of slightly old Dijon mustard to perhaps a more current, fresher shade of beige.
Suddenly, my teeth were maybe a shade or two lighter, putting them in the “non-offensive” category.
They are certainly not blinding, but they are slightly less noticeable.
Importantly, unlike whitening trays I’ve used in the past, my teeth weren’t throbbing with sensitivity after the treatment, which is a huge win.
Subtlety is fine, I guess. People don’t need sunglasses when I walk into a room, but at least I won’t feel compelled to just smile with my mouth closed.
That being said, I can see how after a few weeks of consistent use you might get to the shade you’re looking for.

How much is HeySmile?
Now for the crucial part. A single pack of Hey Smile whitening strips will set you back £19.99.
They sit somewhere in the middle tier—more expensive than drugstore strips called Sellotape, but a lot cheaper than paying a dentist (who would probably tell you to lay off the Earl Gray anyway).
They’re also cheaper than many competitors — Hismile sells 14 treatments worth of strips for £29, while Spotlight Oral Care sells the same number for £44.95.
Where to buy HeySmile
If you were planning a quick trip to Boots or a simple Superdrug shop, think again.
You can only buy them directly from the Hey Smile website or they are also available on Amazon for the same price.

The verdict
So, are Hey Smile teeth whitening strips any good? Yes.
The process takes focus, time and a few uncomfortable minutes, but the end result, when viewed after just one film, is gracious and palpable.
However, if you plan to incorporate them into your daily beauty routine, then this product shines.
It’s a steady, steady piece of maintenance that slowly transforms a stained canvas into a brighter, more presentable smile.
If you like your beauty routines instant and dramatic, then this might not be your solution.
However, if you want to continuously improve the results created over time, these sticky little monsters are a smart choice.
