What kind of scars are these?

Hey guys. I have these two scars on my face that are driving me nuts. I know I shouldn't be complaining about them since they're both small/minor, but I see them, I know they're there, and I have to get rid of them...

This one I've had for quite a while. As a matter of fact, I don't even remember how or when I got it. It's on my right cheek, somewhat below my eye. The picture makes it look much deeper than it really is. I can even stretch my skin a bit and they appear flat. When left alone, it looks like a tiny hole:



This one on the other hand, appeared last month while I was on vacation and is bothering me the most. It is slightly on the left, in the front of my nose. It started as a tiny, insignificant zit. However, for some reason, after it was gone it left this tiny scar. I can also stretch this one a little and it appears flat. It also looks like a very shallow, tiny hole when left alone:




Now for the first one, I know for sure it obviously isn't going to get any better since I've had it for a long time now. The second one on the other hand is quite new and may close up, but I'm starting to doubt it...

So my question is; which form of scar removal would work best for these? I apologize if the pictures aren't clear enough. I can try to take some better ones later.
