How to find the best laser hair removal place for face?

I am white and have medium brown hair, slightly reddish but not always, and I want to get it done on my whole face. I’ve never had laser done before and I know that different lasers have different results! Have you guys ever had laser? How long did it take for your hair to stop growing? Did it work immediately for you?? Does it depend on the person doing it or the machine? How expensive? Know any places in LA? Honestly, just anything helps at this point! Thank you for all help! And please, add anything that could potentially be important!

Thank youu :))❤️❤️
