Are whitening strips safe?
Yes. The safety of the formulation has been evaluated and approved by a qualified assessor.
Can I leave it on overnight?
This is not a leave-on overnight product. ZenyumBright™ Invisible Whitening Strips are designed to dissolve safely in 15-20mins.
Can I use this with invisible braces on?
We don’t recommend it. You can put your invisible braces on after the strip fully dissolves.
My whitening strips don’t work
Make sure the strip is applied flat onto the surface of your teeth, at least twice a day. A 14-day consumer research teeth whitening study among 56 participants in the UK validated that our strips did whiten 4 shades brighter with proper use.
Will it damage bonded teeth?
The product is not to be used on loose teeth/dental restorations.
Is the whitening permanent?
The whitening result will need regular and consistent usage of the product. However the extent and duration of the whitening effect will depend on factors like food/drink consumption, oral hygiene practices, lifestyle choices, inherent teeth colour and discolouration.
Is this product SFA-friendly?
ZenyumBright™ Invisible Whitening Strips meet the stringent regulatory standards for the product type and in the countries we are selling in. The scope of regulatory standards would cover ingredients to the final product.
Does this whiten without sensitivity?
In a consumer study with 56 participants, 93% of consumers expressed no teeth sensitivity. It is further supported by a tooth enamel safety study, in which no dentine or enamel erosion was observed when using the whitening strips. There was also no change in microhardness of the enamel post treatment.
