Over the years, I've tried my fair share of teeth whiteners.
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.
