Best Dual-Ended: Moon Smile Perfector Duo
Why we love it: Moon’s innovative Smile Perfector Duo features a brush-on whitening formula with a color-correcting lip gloss to match. One end of this travel-friendly pen features the brand’s Platinum Advanced Whitening formula, which utilizes urea peroxide (a whitening agent that’s a gentler alternative to hydrogen peroxide) and an antioxidant-rich trifecta of lavender oil, strawberry fruit extract, and honeysuckle flower extract to boost brightening properties and its flavor profile. On the other end of this pen is a moisturizing lip treatment that plumps skin with vitamin E while blue mica pigments neutralize the look of yellow tones on your teeth, creating an instant whitening effect.
Tester feedback: “The Moon Smile Perfector Duo is my go-to for a radiant, selfie-ready smile,” says shopping market editor Angela Trakoshis. “One end whitens my teeth with ease (just brush it on!), and the other is the perfect lip gloss that has pigments to cancel out yellowing tones on my teeth—it’s the perfect finishing touch.”
Key ingredients: urea peroxide, lavender oil, strawberry fruit extract, honeysuckle flower extract | When to use: twice daily for two weeks
Best for Sensitive Teeth: Lumineux Bright Pen
Why we love it: Dr. Castillo recommends the Lumineux Bright Pen for those with sensitivity because “this pen differs from other whitening products in that it is made without peroxide, making it a gentle, yet effective alternative,” she says. Instead of the intensive active, this pen is spiked with a combination of mineral-rich sea salt and coconut oil, sage oil, and lemon peel oil—a trifecta of oils rich in antioxidants to brighten and even the tone of your teeth.
Tester feedback: “My teeth have gotten sensitive with age, so I’m wary of hydrogen peroxide—and prefer this alternative,” says contributing editor Deanna Pai. “It also has a preventative effect, so I’ve been using it before I begin my daily tea routine—which, oops, is otherwise the biggest source of staining for me.”
Key ingredients: sea salt, coconut oil, sage oil, lemon peel oil | When to use: 30 minutes before eating or drinking as needed throughout the day

Most Intensive: Crest 3DWhite Teeth Whitening Pen
Why we love it: Dr. Mustedanagic says Crest’s 3DWhite Teeth Whitening Pen, exactly like the brand’s Allure Best of Beauty Award-winning Whitestrips, contains an intensive combination of hydrogen and carbamide peroxides to provide instant results. “With this pen, you are sure to get results, however, you must use it twice per day for two weeks for the best effects,” he says.
