Beauty editors are blessed with access to virtually every new product and gadget that’s about to hit the market—and that includes teeth-whitening kits. And over the years we've tested a bunch, which makes us the unofficial authority on all smile-related things. Science says that the simple act of smiling has the power to positively impact your mood, lower stress levels, boost your immune system, and possibly even prolong your life. If that doesn't make you want the whitest teeth of your life, I don't know what will.

If you don't want to go the professional route, which can get costly, there are at-home alternatives that deliver professional-level results without your having to sacrifice your savings. And no, they don't require excessive amounts of time and effort. Peroxide, the most popular whitening ingredient, is what makes up most in-office treatments in highly-concentrated doses. However, at-home options also contain peroxide with the same whitening powers. Most of these options ask for 10 minutes or less of your time to grant you lifelong improvements. So to help you get your pearliest whites in the shortest time possible, ahead are the best teeth whiteners on the market that actually, truly work.

Chloe Metzger is the deputy beauty director at Cosmopolitan, obsessively writing about new makeup launches, the best hair products (curly girl here; whattup), and the skincare formulas that really work for every skin type (follow her on Instagram to see behind-the-scenes pics of that magazine life). She also has an unhealthy adoration for Tom Hanks and would like to please meet him one day, if you could arrange that. Thanks.
