Medical Grade vs. Food Grade Hydrogen Peroxide
OSMO WHITENING GEL uses Medical Grade Hydrogen Peroxide:
Hydrogen peroxide solutions are not stable.
To help stabilize the hydrogen peroxide solution, stabilizers are added to ensure consistency of efficacy.
So, the difference is that food grade does not contain any stabilizers, and therefore is not as stable as Medical Grade Hydrogen Peroxide.
OSMO Whitening Gels use MEDICAL GRADE hydrogen peroxide which means your results are consistent and also you won’t get ‘mottled’ results.
