Skin softening and diffusion with trackers?

I'm really fond of the diffusion settings in Magic Bullet Looks but I wonder how you would apply it.
On interview work I like to add a bit of black diffusion but would like to keep the eyes, mouth etc untouched as to
preserve sharpness, what I do in this case is use a mask layer and track the eyes etc and use Looks on top of that layer.
But this method feels a bit dirty and on longer shots is quite a tedious task to fix the tracking points.

So if you would apply some diffusion and softening in post how would you do it?
I noticed Davinci Resolve has some in-build "face trackers" that do exactly that but I don't have it and I wonder how one would emulate this efficiently.
 
Usually in situations such as this one, I like to use a luma matte in combination with an adjustment layer in order to single out a specific area. Although this method is entirely dependent on the color values and how much movement is provided within a particular shot, essentially what you can do "track" and single out just what you need. You can try the following:

1. Duplicate the layer (footage, etc.) you want singled out.
2. Create a luma matte for the duplicated layer.
3. Use an adjustment layer to create a track matte of the duplicated layer (which is now a luma matte).

You can add the necessary effect(s) in After Effects to the adjustment layer and it will only affect the area in which you specify.

I hope this is enough information to get you going in the proper direction, however, if you could attach a single frame of what you are trying to manipulate I be able to help further.

Hmm, looks like it's a luma matte tactic in Resove as well, interesting...sometimes things are so easy :D Thanks for the pointer!
