Crest Whitestrips 1 Hour Express Review

Crest-3D-Luxe-Whitestrips-Professional-Effects-286x300.jpgIn seeking to find the best teeth whitening products on the market, we always review the product from the consumer’s vantage point. After all, it is the consumer who is making the purchase in an effort to get the desired results. This means that we want to ensure not only the efficacy of the teeth whitening strips in question but we also want to ascertain their safety.

With this in mind, the following information is accurate based on the available documentation from the manufacturer, Crest, as well as from our own analysis and that of other customers who have tried the Crest 3D White Luxe Whitestrips Professional Effects 20 Treatments + 3D White Whitestrips 1 Hour Express 2 Treatments.


Since there are two different Crest Whitestrips products within this one kit, let’s look at the ingredients separately before talking about efficacy, potential side effects and what others are saying. First, it is important to understand that there are two very different products you will get in this nice teeth whitening kit. One is designed for daily use and the other, the 1 Hour Express, should be used sparingly, over a longer course of time.

Here are the ingredients for Crest 3D White Luxe Whitestrips Professional Effects.

  • Sodium Hydroxide
  • H2O2 (Hydrogen peroxide)
  • Water
  • PEG-8 (polyethylene glycol esterified with lauric acid)
  • PVP (polyvinylpyrrolidone)
  • Acrylates copolymer
  • Sodium Saccharin

The two main active ingredients in the 20 quantity of Crest 3D White Luxe Whitestrips Professional Effects 20 Treatments + 3D White Whitestrips 1 Hour Express 2 Treatments are hydrogen peroxide and sodium hydroxide. Both are known to be effective bleaching agents as well as antimicrobials. When it comes to whitening up that smile, it helps to kill germs that can lead to further discoloration as well and that’s what these two ingredients do. Of the two ingredients, sodium hydroxide can be the strongest, which we will discuss a bit later on.

As far as the other ingredients go, they serve a purpose but are not bleaching agents. Two are used in the formulation as emulsifiers and gentle adhesives, PEG-8 ad PVP. The substrate on which the ingredients are placed would be the Acrylates copolymer. And, as you can assume the sodium saccharin is a non-caloric sweetening agent to give the whitening strips a pleasant flavor.

The ingredients for the 3D Whitestrips 1 Hour Express are virtually the same as the above with one very important difference! These have a much higher concentration of bleaching agents to promote results in just one hour. The desired result is to bleach years of stains within that hour and based on the ingredients, we find this to be possible. Now let’s look at how easy they are to use and if there are any side effects you should be aware of.

Ease of Use

Of all products on the market, these teeth whitening strips should be amongst the easiest to use. Why? Because of their Advanced Seal Technology. One of the main problems consumers have with other whitening strips is keeping the in place while they do their bleaching. With Crest’s Advanced Seal Technology, this shouldn’t ever be a problem because they were designed with gentle adhesives to keep the strips from slipping out of place. It’s a matter of peeling back the protective sheet, placing them in your mouth and then forgetting they are there for the recommended length of treatment.

Expected Results

Based on the active ingredients and information coming out of independent clinical studies, Crest 3D products can really lift years of built up stains in a much shorter time than other similar products on the market. What consumers hope to accomplish is whiter teeth at a much lower cost than they would be subjected to if they sought professional whitening services from a dentist or a dental hygienist.

Side Effects

In researching the active ingredients, none of them were found to have any serious negative side effects. About the worst that could happen is a bit of stinging and redness from the bleaching agents, but you should know that few people have ever had any allergic reactions to hydrogen peroxide. Sodium hydroxide is a bit stronger and may increase the redness or cause a bit of swelling in some instances, but if it becomes a bit much to handle, simply remove the strips, flush your mouth with plain water and if necessary call your dentist. This is very rare but it does bear mentioning.

What Others Are Saying

In reviewing hundreds of customer comments from around the web and through our own polls, we have found that consumers are really quite satisfied with the Crest 3D products, both the regular treatments and the 1 Hour Express. Few have said they experienced any problems but we did find some who said the peroxide did cause a bit of discomfort at first. They said it was much like how it feels when putting H2O2 on a cut so it just could be that they had some sort of gum infection going on. Without being a dental professional, it’s hard to make that diagnosis.

Our Conclusion

Based on the active ingredients, the known efficacy and safety and most of all what customers are saying, we could wholeheartedly recommend Crest 3D White Luxe Whitestrips Professional Effects 20 Treatments + 3D White Whitestrips 1 Hour Express 2 Treatments – Teeth Whitening Kit. Because of the inclusion of the 1 Hour Express we are happy to rate this product with 4.8 out of 5 possible stars.
