About hi-smile
We believe everyone deserves a confident smile.
hi-smile was built on one simple idea: professional-grade whitening shouldn't require a dentist's chair, a thousand-dollar treatment, or putting your enamel at risk.
Our V34 Colour Corrector Technology uses violet pigment — the same principle behind purple shampoo for blonde hair — to neutralise yellow tones on contact. No peroxide. No sensitivity. Just science that works from the first use.
Our products
Every product in the hi-smile range is formulated to be enamel-safe, sensitivity-free, and dentist-approved. Whether you're using our Whitening Strips for a 30-minute at-home treatment, the Whitening Pen for on-the-go touch-ups, or the V34 Toothpaste as your daily maintenance, the results speak for themselves.
Our promise
If you don't see a visible difference in 14 days, we'll refund you in full. No forms. No return required. Just email us.
