WhiteON products ensure whitening without the risk of damaging the enamel. They contain safe whitening ingredients, such as PAP (phthalimidoperoxycaproic acid) – a unique substance with whitening effects, but that is gentle on the enamel – and enzymes that allow teeth whitening without enamel abrasion. The whitening kit also contains hydroxyapatite, a natural building block of the teeth. WhiteON products do not contain peroxides. The safety and effectiveness of whiteON products has been confirmed by tests supervised by dentists.
