Smile Science Professional Teeth Whitening Strips is a pack of 28 peroxide-free teeth whitening strips which deliver rapid results with noticeably whiter, brighter teeth and a radiant smile without sensitivity. With a formulation developed by a world-renowned dentist, a full 14-day treatment produces teeth up to 6 shades whiter.

The unique elastic gel consistency, combined with advanced moulding technology, enhances the strip's cohesion to the teeth, resisting the loosening action of saliva and allowing the strips to deliver intensive stain removal. The innovative peroxide-free formulation contained within the teeth whitening strips has a gentle, enamel-friendly action, avoiding sensitivity, discomfort or other side-effects, both during and after use.

Designed for user comfort, the strips target both surface and deeper stains caused by tea, coffee, smoking and red wine, with continued use in line with the instructions producing professional level results. Cruelty-free & vegan-friendly.

Directions of use:

  • Remove the first whitening strip from the pouch.
  • Pull away the soft strip from the plastic film.
  • With the help of a mirror, align the straight edge of the strip to the gum line.
  • Gently exert some pressure and adjust the strip with the finger so that it adheres to the tooth surface completely.
  • Repeat using the second strip.
  • After 30 minutes of application, remove the strips and dispense.
  • Remove any residue of the gel using a toothbrush and water only.
  • Use both strips provided in the pouch, one for the upper arch and one for the lower arch of the teeth.
  • Avoid application of the strips after brushing your teeth.
  • Use before going to bed and refrain from eating.
