I’m a serious coffee drinker, so in an effort to keep my pearly whites, well, white, it’s pretty much always been a priority beauty practice. First there were the pricey custom-fit trays from the dentist, then came good, ol’ Crest White Strips and, now, the LED-whitening trays taking Instagram by storm. Specifically, I tried the HiSmile kit (admittedly because it’s a brand Kylie Jenner openly backs). No, I wasn’t nonchalantly whitening away in my matching undies like a certain reality star. For me, it was usually late in the evening, in bed, watching Netflix with zit cream on—a much less sexy scene. But nonetheless, I followed the same program.
When it comes to teeth whitening products, you want to be weary of Peroxide (it’s a big no-no that will make your teeth sensitive and it tastes awful). Though HiSmile’s formula doesn’t include the bleaching agent, it did however still have that somewhat familiar, off-putting taste (just less intense).
As for the actual whitening, the box said 10 minutes a day was all it took, which was nothing compared to the 30-plus minutes I used to spend doing Crest White Strips. The process was fairly intuitive: Just line the front sides of the trays with the clear gel, pop the device into your mouth, turn on the LED light (which helps expedite the whitening) and let it sit for 10 minutes until it turned itself off. The hardest part was pressing the trays firmly against my teeth without clenching and getting a headache—not easy. Once the light beeped off, out the trays went. I lightly swished water in my mouth to get rid of any of the remaining gel residue and that was it.
