Best Double Ending: Moon Smile Perfector Duo
Why we love it: Moon’s innovative Smile Perfector Duo features a whitening formula with a lip gloss brush that corrects the color to match. One end of this travel-friendly pen features the brand’s Platinum Advanced Whitening Formula, which uses urea peroxide (a whitening agent that’s a milder alternative to hydrogen peroxide) and an antioxidant-rich trifecta of lavender oil, extract strawberry fruit and honeysuckle flower extract to enhance its brightening properties and flavor profile. On the other end of this pen is a hydrating lip treatment that infuses the skin with vitamin E while blue mica pigments neutralize the appearance of yellow tones on your teeth, creating an immediate whitening effect.
Comments from testers: “Moon Smile Perfector Duo is my go-to glowy, 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 the yellow 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 a day for two weeks
Best for sensitive teeth: Lumineux light pen
Why we love it: Dr. Castillo recommends the Lumineux Bright Pen for people with sensitivity because “this pen differs from other whitening products in that it’s made without peroxide, making it a gentle, yet effective alternative,” she says. Instead of the intensive active, this pen is packed with a combination of sea salt and mineral-rich coconut oil, clary sage oil and lemon peel oil – a clover of antioxidant-rich oils to brighten and even tone your teeth.
Comments from testers: “My teeth have become sensitive with age, so I’m wary of hydrogen peroxide—and prefer this alternative,” says editor Deanna Pai. “It also has a preventative effect, so I’ve been using it before starting my daily tea routine – which, oops, is otherwise my biggest source of blemishes.”
Key Ingredients: sea ​​salt, coconut oil, sage oil, lemon peel oil | When to use: 30 minutes before eating or drinking as needed during the day

More intensive: Crest 3DWhite teeth whitening pen
Why we love it: Dr. Mustedanagic says Crest’s 3DWhite teeth whitening pen, just like the brand’s Allure Best of Beauty Award Whitestrips contain an intense combination of hydrogen and carbamide peroxides to deliver immediate results. “With this pen, you are sure to get results, however, you need to use it twice a day for two weeks for the best results,” he says.
