Now, let's talk about teeth whitening. (Open in new tab) I am obviously part of the "teeth can always be whiter" school of thought, and I have sat in many dentist chairs over the years because of this fact. However, on days when I can't be bothered to go to the dentist or leave the house, I use Crest 3D White Professional Effects Whitestrips (opens in new tab). Honestly, it works better than the dentist's stains.

The top-rated at-home whitening kit (opens in new tab) claims to remove 14 years worth of stains in just a 30-minute session and has garnered nearly 40,000 five-star reviews on Amazon. That's because it's currently on sale for $27.96 as part of Amazon's Holiday Beauty Haul event. Originally priced at $47.99, it was never that expensive to begin with, but it has always been blessed with good sales lately.

The 3D White Professional Effects White Strips would not garner such praise if they weren't ridiculously easy to use. Here's how to use it: Press the thin, flexible strip against your teeth and leave it for 30 minutes. That's it!

Each strip is designed to stay in place after application, allowing you to eat, drink, and otherwise live freely while it is in place. You can use them daily if you want a super bright look, or use them intermittently for a more gradual look.

I am officially an at-home teeth whitening convert, so forgive me while I show off my shiny white teeth with fair-weird parents' La Chanel chip skylarks.
