Rated 2 out of 5 Stars

If you want to whiten your teeth at home, the Rembrandt Deeply White 2-Hour Whitening Kit promises to whiten your teeth noticeably in just two hours. The whitening treatment is split into 4 20-minute sessions with a 10-minute break in between them.

The active ingredient in Rembrandt 2-hour whitening kit is hydrogen peroxide, one of the most used whitening substances. However, according to an EU regulation, all whitening kits for home use should not contain more than 0.1% hydrogen peroxide, but we cannot say if it conforms with the EU law as the ingredient list does not mention the hydrogen peroxide concentration.


As mentioned on the packaging, the ingredients are:

Water (eau), Glycerine, Hydrogen Peroxide, Peg-40 Hydrogenated Castor Oil, Carbomer, Aroma (Flavour), Potassium Hydroxide, Menthol, Calcium Disodium EDTA, Sodium Saccharin.

The whitening kit contains 8ml of whitening gel.

How to Use

Step 1: First of all, you should mould the mouth trays. This is easily done if you leave them in hot water for 5 seconds. While still warm, bite hard on them to make them take the shape of your teeth.

Step 2: Apply a very thin line of gel in each mouth tray and fit them over your teeth. Use a q-tip to wipe off any extra gel that may escape on your gums in order to prevent swelling or a burning sensation. Leave the mouth trays on for 20 minutes. Remove and rinse your mouth well. Wait for 10 minutes and repeat step 2. Do it 4 times in total. This will take you about 2 hours – as the name of the product suggests.

The company suggests using the product every six months to maintain the whitening results, but they also recommend the daily use of Rembrandt whitening toothpaste or whitening mouthwash.
















Even though Rembrandt 2-Hour Whitening Kit is one of the oldest whitening kits on the market, there are a large number of users who either experienced pain and sensitivity, or they did not have the results they expected. Based on a large number of reviews on, only 57% of users seem to be so satisfied as to recommend the product.

We are also hesitant to recommend the product, both because of its unpleasant side effects and because we don’t know if it breaks the EU regulations as far as its concentration of hydrogen peroxide is concerned.
