how do I get a webcam for my gaming videos?

I've been doing lots of gaming on my youtube channel, and well, I want to have a webcam.
I'm on a macbook air and I can't find any ways to have a webcam.
Nothing is working for me.

what do you wanna use it for? To show yourself while gaming or the game itself?

I want to show my face in the corner of my screen while I'm gaming.
