A bit pricey but I recommend everyone trying these before getting a professional teeth whitening job done. They are super easy to use and definitely work over a period of weeks. I usually have some left over in the box after purchasing that I can touch up with.

I have years of built up coffee/wine stains that have made me embarassed of my smile. I noticed a pretty impressive difference in the color of my teeth after using this just once, & it’s become my new addiction. I do have pretty sensitive teeth, so using this once a week is enough for me.

Uncleared instructions

I have received my package. I’m at my third treatment so far no results. However I’m very confident it’s too early to have noticiable results as my teeth are not extremely stained. But looking forward to whiter teeth after my active braces treatment. The only confusion I have is that I have just noticed than in this website the suggested time per treatment is 30 min. However in the box says 45 minutes. May I please get assistance on how many minutes should I leave the strips on.

Affordable way to whiten your teeth at home

[This review was collected as part of a promotion.] I recently tried the Crest 3DWhitestrips Professional Effects, and I can honestly say—they live up to the hype. I started seeing a difference after just 3 uses, and by the end of the 20-day treatment, my teeth were visibly whiter—like two shades lighter at least. Each strip fits well and stays in place (upper and lower), so I could still talk or move around without it slipping. It gave results similar to what I’ve gotten from in-office whitening—without the high price tag. I was worried about sensitivity, but I only had mild tingling once or twice. I used a sensitivity toothpaste during the process, which helped. If you have very sensitive teeth, start slow—maybe every other day—just to be safe.

Old strips were much better

I used the Crest Classic Whitening Strips previously and had great results (didn't even need to use the entire box at one time to get the results I wanted). I was quite disappointed that the Professional Effects did absolutely nothing to whiten my teeth. They did stay put much better, however. I do not have subborn stains or overly yellowed teeth; I'm not a smoker but I do drink coffee. I just wanted to give my smile a brightening boost. Unfortunately, I will be looking for other whitening products unless the Crest Classic Whitening Strips return to the market. Luckily I was able to get a refund.

Not what I was expecting

I have used this product in the past and it worked like I would have imagined I was vary happy. I stopped using it since it was a little expensive for me. I recently bought this product again and I see almost no results then before. I don't smoke or drink coffee and expected the same results as it used to provide. Maybe there something wrong thins time with the product. I do wish to have my money back or a discount to buy another box and see if there is something wrong with the product or just the one I bought.

Never Again

One of the most ridiculous and unfriendly kinds of packaging I've ever experienced. You need a buzz saw and armor to open a huge hard plastic/cardboard covering for two boxes which then contain feather light strips probably not weighing 1/2 oz. Not only a detriment to the environment but to the consumer!! Not worth the cuts, bruises and time to get to the little prize inside.

I got a 2 pack of 40 whitening strips. I used to use them about everyday for 30 minutes, but then forgot about it and got busy. When I was doing it everyday, I could see progress with my teeth, but then it went away when I stopped being in the routine of doing it everyday.

What happened to Luxe?

Used Professional Effects in the past with AMAZING results, as have many of my friends and family. So many people swore by it — and for good reason! It did exactly what it promised. So why on earth change something that was already perfected and loved by many? Change is not always for the best. The purple boxed Luxe should have been a permanent product. These new strips neither adhere sufficiently, nor whitens evenly, or even half as well as the former ones. Extremely disappointed in the change of line. I'll never understand why companies feel the need to "update" products that WORK. If it does what it's supposed to and impresses people with the results, then leave it alone! Loyal consumers will thank you by coming back for more. As it stands now, I will not be wasting further money on this overpriced junk. A real shame, since I would have repeated my purchases on the older strips for as long as it was available/needed. Don't cheapen your products. You were doing good work before.
