An unfortunate fact of life is that — unless you’ve actually been wearing your retainer every night for the past 20 years like your orthodontist told you to (oops!) — you might not have perfectly straight teeth. Those people can find it difficult to use whitening strips, since they come in one size and shape. The Tarte pen is a great solution to that problem, as it lets you paint each individual tooth for an even application, thanks to its soft-bristle brush and gel designed to cling to teeth for “360-degree effects” — a success for straight and uneven teeth alike.
While you do have to apply it four times a day, the overall time commitment is still less than most strips, which often require you to stay put for 30 minutes to an hour. And reviewers noted that the tube is about the size of a lipstick, making it easy to use on the go. The site even recommends using it “post-coffee,” which is great for people like me who can just see our teeth getting yellower with each sip of coffee.
Granted, it takes a little longer to see the same level of whitening as with our $$ pick, Crest Whitestrips (hence the multiple times a day), but if you’re looking for a safe bet that’s pain-free and cruelty-free, this treatment is for you.
Get it from Sephora for $22, from Tarte for $22, or from JCPenney for $22.
