Feels like a lipgloss. Instructions are easy to understand. It doesn't dry at all and good results with repetitive use . Wouldn't repurchase though

This product is just a marketing gimmick that promises whiter teeth but fails miserably. I've been using this product twice a day for over a month and don't see any improvement. Unlike other brands that highlight the high percentage of hydrogen peroxide in their whitening products, Crest doesn't disclose that info on their packaging or in online ads which. leads me to believe they have something to hide. The over-the-counter whiteners simply don't contain the same high hydrogen peroxide content that will give you the light & bright smile you can only get in your dentist's office.

Used it on 8 lower teeth and saw no difference, and I used several times a day!

I've been using these crest white strips for years and have found them to be extremely effective for me. They always whiten my teeth several shades and I never experience any major sensitivity with them. I'll always repurchase these!

I've been using the Crest 3D White Monthly Whitening Boost Whitestrips for a few months now, and I'm really pleased with the results. They noticeably brighten my teeth after each use and help maintain a whiter smile between professional cleanings. The strips are easy to apply and stay in place, and I love the convenience of the monthly use. I did experience some mild sensitivity, but nothing too uncomfortable. The packaging is compact and makes storage simple. I gave it 4 stars because I wish the whitening lasted a bit longer, but overall it's a great at-home boost.

Very effective product. Does cause some sensitivity in me, but I tend to be very sensitive to these kind of products so maybe it's me. Nevertheless, people always comment on how white my smile is and I honestly am not even super consistent with it.

I've been using these for years!!! My teeth stay white and all the stains are gone. I recommend to everyone! Definitely follow the instructions because that's how you'll get the best results

I use these monthly and get the so many compliments on my teeth! The value is fair, you get a significant amount of strips for the price. They do not cause too much sensitivity as long as you don't keep them on longer than you should. I love these!

I love these white strips! They don't leave my teeth achy and leave them more white. Overall a great product and very high quality especially for the price.

I definitely saw a large improvement in the whiteness of my teeth while using these. It's easy to through them on and go about my night. My only complaint is I did experience some sensitivity to cold food, but this went away when I stopped using the strips as often
