The SunnaSmile gel absorbs the LED light energy, which photo-chemically "excites" the peroxide molecules into breaking down faster. It provides "activating energy" that speeds up and improves the performance of whitening.
The SunnaSmile LED light activates the professional whitening gel upon contact to provide visible results in just 20 minutes! Stick with it for 5 days and you’ll take your teeth up to 8 shades whiter.
The SunnaSmile in-studio treatment formula is slightly more potent than the at-home kit, removing years of built up stains and discolouration in just 15 minutes.
