How 2 do makeup on scarred face?

So after a good long while (few years) of depression lingering in the background of my life my face has become scarred by acne from a lack/bare minimum of self care. Like REALLY scarred. So now that I'm taking better care of myself I have 2 questions:

1) Is there a way to do makeup that can sort of minimise that scarring?

and

2) Even if now, how do I do makeup in general? Like just basic rundown and tips would be appreciated :D

I'm 6teen and feel really ridiculous at the fact idk how to and whenever some minimal lipstick or some shit was applied to me I felt kinda like a clown</3 I want to actually try :P

Any advice would be appreciated!! :D

(Wasn't really sure which category 2 post this in)
