No, the ALPINE WHITE formula was developed in collaboration with Swiss dentists and dental experts. The tooth-friendly formulation is based on very effective ingredients but does not contain any harmful bleaching agents, such as the commonly used hydrogen peroxide. Instead, teeth are whitened with the active ingredients phthalimidoperoxycaproic acid (PAP), hydroxyapatite and potassium nitrate. These provide the gentle whitening effect, while at the same time supporting shine and enamel build-up and alleviating existing tooth sensitivities.
