Why trust us?

After just 30 minutes of use, I saw visible results
Surprisingly, it doesn’t lean on peroxide, opting rather for a combination of PAP (a gentle whitening ingredient, with the full chemical name phthalimidoperoxycaproic acid) and LED activation.

The kit uses blue light to accelerate the PAP’s stain-removal process, aiming to minimise discolouration from coffee, wine and food and drink more broadly.

All without putting your enamel at risk.

Balancing value for money and noticeable results, this was (and continues to be) the kit I reach for when my teeth need some TLC.

I tracked my results over the course of a full treatment cycle to show how SmilePro delivers on its promises, including filming my application and whitened teeth.

Scroll on for my honest verdict.

SmilePro advanced teeth whitening kit
Smilepro’s LED teeth whitening kit offers a complete solution for brighter teeth, with both blue and red light settings.

The blue light accelerates stain removal by boosting the performance of the PAP as it oxidises discolouration.

Meanwhile, the red light helps to reduce gum inflammation, tooth sensitivity, and bacteria.

For a more comprehensive whitening experience, you can combine both lights in a third setting.

The mouth tray is comfortable to wear – albeit a bit of a jaw workout for half an hour – and using the kit is easy: apply the gel, insert the tray, and activate the blue, red or dual LED light.

However, one drawback is the overly sensitive touch-activated power button, which can be easily triggered, turning the device off or switching modes unexpectedly.

As someone who likes to multitask while whitening, the button was a little unhelpful when trying to cleanse and moisturise mid-session.

While the brand claims visible results can be seen after seven days of 10-minute treatments, I personally saw noticeable improvements after just one 30-minute session – specifically, using the included guide, a difference of at least one shade.

By the end of my seven-day rotation, I couldn’t attest to SmilePro’s promise of “eight shades whiter”, but I certainly saw a visible and worthwhile lift.

It’s worth noting that I have recently used other whitening kits, so I can appreciate that the kit didn’t have as much staining to work with.

With enough formula for 30 treatments or four full cycles, there’s no denying that SmilePro’s advanced teeth whitening kit offers solid value – especially with the current 50 per cent discount, bringing the price to less than £50.

The LED mouth tray was easy to wear and operate (including faff-free USB charging) and the serum was simple to apply.

I loved how it didn’t warrant an extra brushing session to rid your mouth of any serum stickiness or unpleasant tastes.

In fact, a quick rinse afterwards was all I needed and, even then, it felt like more of a formality.

On the whole, I enjoyed the increased brilliance of my teeth after each treatment and I’ll certainly be reaching for my subsequent three whitening cycles as my iced coffee consumption increases over the summer months.

Staining, be gone!

Following the brand’s instructions, I tested SmilePro’s advanced whitening kit for 10-30 minutes daily over a period of seven days.

While a single treatment using the LED mouthguard spans 10 minutes, I adhered to the upper limit session times and proceeded to reactivate the light twice over for a total of 30 minutes’ wear.

To use, I had to coat the visible teeth with the included dental-grade formula.

After applying (and avoiding moistening the newly-coated teeth), I then applied the mouth guard and activated the blue LEDs using the touch power button.

While I maintained use of the blue light mode throughout my testing, the SmilePro device does afford users additional gum/tooth sensitivity protection with the addition of red light and dual blue-red light modes.

When testing, I factored in the following criteria while testing:
