One thought on “HOW LONG DOES THE WHITENING PEL/PEN LAST?”
Optic White™ Toothbrush has been specially designed to remove surface stains and the Optic White™ gel contains peroxide, to deeply and safely whiten. Studies have shown no harmful effects on tooth enamel when used as directed. Yes. Per the instructions on pack, if the whitening gel is used every day, twice a day, the pen lasts approximately three weeks. In those instances, the pen typically lasts between 6-12 weeks. However, usage studies found that once consumers start seeing results (within ~1 week), they become less diligent about about application. Make sure you put the lid on the pen or store it inside the toothbrush. We recommend doing so because improper storage of the pen increases the likelihood of introducing moisture and other foreign particles into the product, which in turn can cause product instability.
