How GLO uses H2 O2

GLO never uses carbamide peroxide, and the gel therefore has no harmful breakdown byproducts (ammonia, urea, alcohol) that can cause irritation to the teeth and gums. In the dental practice, the whitening gel is delivered in a dual-barrel syringe that also includes a pH raiser and a special desensitizing agent. The lower 24% formulation is specially designed for younger patients and those with dentinal sensitivity, recession, and abfraction at the CEJ. At home, patients use innovative GLO Vial whitening gel, containing 10% purified hydrogen peroxide in an adhesive form (peroxydone). The Vials feature a unique brush tip applicator to allow for targeted, precise application as well as a highly adhesive gel formulation that stays put on the teeth, without migrating onto the soft tissue.
