FOREO Lilac Purple Issa Dual LED + Sonic Teeth Whitening Kit

'issa™ Teeth Whitening Set HOW TO USE: 1. APPLY GEL: Brush your teeth to remove excess plaque and food - for optimal results, we recommend using a FOREO issa™ toothbrush. Unscrew the top of the issa™ advanced teeth whitening gel syringe & apply a quarter of the syringe to the base of each side of the mouth tray (half a syringe in total). 2. TREAT WITH DEVICE: Place the tray in your mouth & press the universal power button to turn on your device. Press the button again to cycle between different modes: blue+red LED for teeth whitening+gum care, blue LED for teeth whitening only, or red LED for gum care only. 3. RINSE MOUTH: Your device will automatically turn off after 15 mins. Once the session is finished, rinse your mouth thoroughly with water. For maximum results, complete a full treatment by repeating daily for 6 consecutive days - and enjoy visibly whiter, brighter teeth.
