Many of you interested in teeth whitening
probably heard of "blue light" rays before!
Put your hands in the air if you are a Little Bean who used teeth whitening devices~
or teeth whitening products with blue lights before!🙋\u200d♂️
Unfortunately....
Blue LED lights do absolutely~~ nothing~~ for teeth whitening!
You will see numerous products being sold
such as [Teeth whitening agent + blue LED]!
Why? How? Does blue LED have no effect?
There are even products which emphasize
blue light, without whitening agents, are enough to whiten the teeth!🤔
The reason for no effect of blue light on teeth whitening~?
