Aura around someone’s head
I made a circle mask on an adjustment layer, which will move after the head of the character. Problem is that it shines the face itself, and I want it to be around the head. The invert makes the layer black, see picture below.
What can I do to make the aura around the head’ and being moved??

The computer doesn’t know what is “head” and what is “background” in the footage. All it sees are lights, darks, and colours.
So you have to tell it what is head, and what is background. If the person were shot on a greenscreen, you could tell the computer “green is background, everything else is foreground — cut it out”.
However, this was not shot on greenscreen, so you have to use the pen tool to draw a mask around the person’s head. This is called “rotoscoping”, or “roto”. The process is in the help under “animating masks”, or something like that.
Once you read up on that, here’s a hint: only set mask shape keyframes when the direction of shape movement changes. let AE interpolate between.

I had to duplicate a second mask on that same (solid) layer and to change it to Subtract, in the center of the bigger visible mask:
