Coffee, tea and red wine slowly dull your smile, and many brightening products leave teeth sensitive. Blue light brightens with your gel, red light soothes in between, so you can smile in every photo without the sting.
Brighten gently with multi-spectrum light
What research says about light, brightening gels and sensitivity.
What research shows
Reviews show the brightening gel does most of the work and the added value of light is still debated, so a gentle gel and steady routine matter most.
Why it works
Blue light is paired with your gel to support the brightening process, while red light soothes teeth and gums so sensitivity doesn't stop your routine.
Relevant light modes
Blue for brightening, Red for comfort, and Purple (Red + Blue) for an all-round fresh, clean feel. Visible light only, with no UV.
