How do smoking and bleaching interact?
Normally, it is recommended to refrain from smoking after a bleaching treatment because smoke interacts with the bleaching active principles.
With the BlancOne® bleaching treatments it is recommended not to smoke for a couple of days. If that is just not possible, it is recommended to blow the smoke out through the nose for a couple of days after the treatment since the interaction occurs with the smoke that is breathed out.
Besides being harmful to your health, smoking will also reduce your bleaching effects over time.
