In recent years, LED light therapy has been making waves in the beauty industry. From red-light facials that can deliver 'glass skin' (a popular Korean beauty trend is so luminous and clear it looks like a sheet of glass) to blue-light masks that combat acne breakouts, these bulbs have quickly become a skincare staple. 

But what if we told you that it's not just your skin that LED light therapy can supercharge? It also has the power to whiten your teeth more effectively than any other at-home dental product. 

Enter SmilePro’s Advanced Whitening Kit. The portable device is backed by over 5,000 five-star reviews and has earned itself cult-status on social media platforms like TikTok and Instagram.

Unlike whitening strips or toothpastes that only skim the surface, SmilePro pairs a peroxide-based and professional-grade whitening gel with dual LED lighting. The result is nashers that are up to eight shades whiter, without any sensitivity or a hefty dentist bill.

The details

  • Formulated to deliver professional whitening results at home for less than £2 per treatment
  • Teeth can go up to eight shades whiter thanks to the system having triple the amount of activator LED lights than any other kit on the market
  • Enamel safe, sensitivity-free formula in the professional-grade whitening gel
  • Permanently removes smoking, coffee, soda, and wine stains within 10 minutes

And what better time to elevate your dental regime than with Black Friday discounts attached? From 25 November to 1 December, SmilePro will be slashing the price of its coveted whitening system by up to 60% on the SmilePro website. Right on time for festive photo opportunities!

 A closer look at the SmilePro's Advanced Teeth Whitening Kit

While most whitening strips simply bleach the surface of teeth, SmilePro takes a more scientific approach. The peroxide-based gel is paired with dual LED lights across blue and red spectrums:

  • Blue light works as an accelerator, helping the formula break down stubborn stains from things like coffee, wine and food
  • Red light soothes gums, reduces inflammation and targets bacteria that can cause bad breath

This two-in-one system not only promises up to eight shades whiter teeth but also keeps your mouth feeling healthy and irritation-free, all without a hefty dentist bill.

What verified shoppers say about SmilePro…

Users say results can be seen in as little as a single session, with the full 30-day course offering a transformation of up to eight shades. And with treatments working out at just £2 each, it’s far more affordable than professional whitening.
