Yes. The Whitening Pen can be used together with your LED whitening light to help accelerate your whitening results. Simply apply a thin, even layer of whitening gel from the pen directly to the front surface of your teeth as you normally would, then insert the LED whitening light into your mouth and use it for 30 minutes. The LED light helps enhance the whitening process, allowing you to achieve brighter results more quickly than using the Whitening Pen alone.
