Sigrid

What you have is two equivalent products. Either is intended to provide a similar whitening process and create a similar level of results.

Whitening results are simply cause and effect, based on the total exposure of your teeth to the whitener.

The Luxe Glamours White product has a 9.5% hydrogen peroxide whitener that is on your teeth for 30 minutes a day, for 14 days.

The Express product has a 10% hydrogen peroxide whitener that is on your teeth for 60 minutes a day, for 7 days.

Both products will deliver a similar cumulative exposure of whitener to your teeth, and therefore can be expected to create a similar whitening result.

Using both products over the same time frame would equate to double treatments. That is not advised. Side effects would likely be a problem for you.

Choose whichever kit seems most attractive to you and use it alone. Save the other kit for somewhere later on down the line. Store the unused kit in a dark, cool place (your refrigerator).
