I wasn't expecting to notice such a difference so quickly, but after three treatments my skin looks brighter, plumper and much more even. My makeup goes on more smoothly and I've actually started wearing less of it because my skin looks so much healthier on it's own.

I've always had deeper lines around my jaw and mouth, and over the years they've become one of the first things I notice when I look in the mirror. I wasn't expecting dramatic results. My skin looks smoother, feels firmer and those lines don't look nearly as pronounced.

I received my smile package yesterday. I used the strips last night and then the toothpaste this morning and already a huge change. I drink coffee a lot and these other toothpastes couldn’t get rid of my stains, I’m so impressed with this product. Can’t wait to use the Boost Kit!

I was hoping for a bit of a difference, but the results completely blew me away! I've always been someone who has struggled with self confidence, the "boost" this has given me is hard to put into words. I highly recommend Smilie's Whitening Kit to anyone who is on the fence, you wont regret it!

I've struggled with redness for as long as I can remember. No matter what I tried, my skin always looked flushed and uneven. After just three treatments with Smilie's Advanced Peptide Serum, I couldn't believe the difference. The redness has reduced so much, my skin looks calmer and more even.

Questions?
We’re here to help.

We know you probably have a few. Here are the ones we hear most - and if yours isn't here, our team is always happy to help

Is there a money-back guarantee?

Yes, and we mean it. Every Smilie product comes with a 30-day Money-Back Guarantee. If you've given it a real go and you're not seeing the results you expected, we'll refund you. We're confident in what we make, and we want you to feel the same way before you commit
What makes Smilie's Boost Teeth Whitening Kit different?

The Smilie Boost Whitening Kit is designed with the same professional-grade ingredients dentists use, but at a lower and safer concentration - so you get effective whitening without harshness. What truly sets it apart is the added Potassium Nitrate, a proven ingredient that helps calm and protect sensitive teeth while you whiten. This means you don’t just get a brighter smile - you get it comfortably, without the pain that many other whitening kits can cause.
Are Smilie products safe to use?

Yes. Every product is dentist-developed and dermatologist-considered. Our whitening formula is sensitivity-free by design, and our beauty devices are built to professional standards for safe at-home use.
I have sensitive teeth or skin - can I still use Smilie?

Sensitivity is something we take seriously. Our whitening formulations are specifically designed to minimise sensitivity while still delivering real results, and our devices are built with adjustable settings so you can work at your own pace. That said, if you have a specific condition or concern, please reach out to our team.
