- Gently brush teeth with toothpaste
- Take both batteries out of the Pearl Activating Light, remove plastic and reinsert the batteries with the writing side facing up
- Attach the mouth tray to the led light
- Dry your teeth and then twist the pen and generously apply the serum directly onto your teeth. Ensuring you get close to the gum line (it helps to use a mirror)
- Put the light in your mouth and turn the light on
- Wait for light to turn off after 10 minutes
- Rinse mouth out with warm water
**TIP** - You can leave the formula on for 30 minutes for maximum effect. We recommend leaving the light in your mouth as it stops saliva from getting onto your teeth and mixing with the gel.
