How safe is laser hair removal treatment & what is its total operating cost?

I have some unwanted hairs on my face.
I want to get rid of them permanently.
Please suggest some efficient treatment without amy side effects.

I am thinking of going for a laser removal of those probably Beard Shaping.
So how safe is that. Is there any side effects of that treatment.
Also what could be the total cost and treatment duration of such procedures?

Thanks in Anticipation!
