Gel Refills

Our Gel Refills include 3 additional Gel Syringes, to resupply your Teeth Whitening Kit and help maintain or improve your results. Depending on your consumption of dark foods, everyday stains may start to creep back in after your initial treatment. By keeping your Kit stocked with Gel Refills you’ll ensure that your teeth stay whiter and brighter for longer.

After your first 6 day treatment results can last between 3-4 weeks. For longer lasting results, try to limit your intake of any dark foods or drinks that stain teeth. This includes coffee and tea, wine, pasta and curry sauces, and even some fruits and berries.

To keep your teeth white and bright, we recommend completing a single use of the HiSmile Teeth Whitening Kit every 2 weeks after your initial round of whitening.

HiSmile’s new and improved whitening formula is completely vegan and peroxide-free. The three active ingredients in our formula are Phthalimidoperoxyxcaproic Acid (PAP), Hydroxyapatite, and Potassium Nitrate.

PAP is our active whitening ingredient, which whitens discoloured molecules inside teeth. Hydroxyapatite is our active repairing ingredient, that remineralises and strengthens teeth. Potassium Nitrate is our active soothing ingredient, it protects the nerve and desensitises teeth.

Full ingredients:

Sorbitol, Water, Phthalimidoperoxycaproic Acid, Propylene Glycol, Glycerin, Potassium Nitrate, PEG-8, Hydroxyapatite, Cellulose Gum, Hydroxyethylcellulose, Xanthan Gum, Flavour, Sodium Saccharin, Methylparaben, Sodium Bicarbonate, Aloe Barbadensis (Aloe Vera) Leaf Extract, Chamomilla Recutita Flower (Chamomile) Extract, Punica Granatum Seed (Pomegranate) Extract, Propylparaben

Phthalimidoperoxyxcaproic Acid (PAP) is the primary whitening agent used in HiSmile’s Teeth Whitening Kit which is completely safe for your teeth. PAP oxidises tooth stains and creates lighter compounds within your teeth to produce a whitening effect. It’s proven to whiten teeth as effectively as traditional ingredients, with the added bonus of not causing enamel damage and tooth demineralisation that come with traditional whitening ingredients.

The biggest difference to our formula is a change in our active ingredients. Our old formula contained Sodium Bicarbonate and Sodium Chlorite as primary whitening agents. In our new formula, Phthalimidoperoxycaproic Acid (PAP) acts as the primary whitening ingredient. PAP whitens teeth through oxidisation, which we found to be a more effective process than Sodium Bicarbonate’s mildly abrasive action.

The new formula also introduces Hydroxyapatite and Potassium Nitrate as active ingredients. Hydroxyapatite strengthens and remineralises teeth, while Potassium Nitrate protects from sensitivity. The result is a formula that delivers better results than ever before, without any pain or sensitivity.
