These Crest 3D Whitestrips with LED Light Promise Professional-Looking Results...But Are They Worth It?

When it comes to whitening strips, Crest is a household name, as they practically built the market for at-home teeth whitening products. However, while we're used to the brand's classic, stick-on strips, we're curious whether their 1-Hour Express Whitestrips + LED Light kit ($49) is worth the price tag and the time.

In the latest episode of PureWow's Take My Money YouTube series creator Kate tests the kit out for 19 days, showing viewers the results on her (hopefully) pearly whites. Check it out below.

As demonstrated by Kate, the pack comes with strips for 19 days, as well as a mouth light. You can complete the process by applying the strips each day, leaving them on for an hour. Then, once the hour is up, you insert the mouth light for 5 minutes, before removing it and peeling off the strips. Voila!

So does the process make a big difference? You'll have to watch the full video above to find out. Meanwhile, you can shop the product below (which, as Kate notes, retails for $85, but is typically sold for $49 on Amazon).
