Does the teeth whitening light actually work?

I have noticed a ton of Instagram models advertising the teeth whitening light. I have a couple questions about it; first off does it actually work or is it a marketing ploy? Secondly, is this type of whitening dangerous to your teeth's enamel. I would hate to compromise a bit whiter teeth if it is hurting my enamel. Thanks so much!

The whitening light does work without damage to your teeth when it is performed in a dental office under professional supervision. Any of the over the counter systems won't generally work as well.
