black marks everywhere i used a mask

I assume from the screenshot that layers 1 and 2 are the fill layers because they are named Fill. I can't tell if there are any layers below layer 3. That is where the fill needs to go. You also do not have any keyframes for the masks, so I am guessing that the actor does not move or you have not yet animated the masks. The blackmarks are probably not black. They are probably holes. You can check that by enabling the Transparency Grid. 

There are lots of different ways to remove blemishes. Masking is probably the least efficient way to do that.

The most efficient workflow depends on the shot, the problems you must fix, and the tools you have to work with. Boris FX Beauty Studio will do wonders with all kinds of shots, but it's a 3rd party plug-in that costs money. Some solutions require motion tracking, cloning, and a combination of effects. Some are as simple as adding some blur, color correction, and changing the blend mode of a copy of the footage above the original.

If I saw a full frame of the original footage and had a description of the motion in the frame, I could offer some more detailed suggestions.

In the future, please drag your screenshots to the reply field or copy and paste the file, or use the toolbar to embed the images so we can see them without downloading them. Try not to use the Drag and Drop here button for anything but project files and short movies that you can't share in another way.
