is there a way to create easily a texture skin from a face picture (front/back/left/right)? I mean, is there a tool to transform a face picture into this texture skin (face part)?

Quick answer, you might have guessed it, is: no. Very unfortunately, as far as i know, until present even the proprietary solutions are not what i would call easy. It's called photogrammetry. You make dozends of images from different angles, you disable auto-exposure at your camera for a constant light, you kill your model so it can't move, you resize them a bit unless you work for NASA, you clean up the voxels, you put that into a remesher, you tweak it, you import it into blender, you transfer UV's, and there you are!
Piece of cake. And all that is available as open source as well in your favourite internet.
Hence, projection paint in blender seems to be easier still. On the blender side, we can't expect many improvements in that area, since they are working on the next big general change (blender 3.0), so not only no time for new ideas, but also a kind of rushed results. I won't be surprised to see a version 2.78d in the next weeks, because everyone is stressed by their own expectations, and everything is knitted with a hot needle, so there are many bugs.
But maybe, in the long run, if the MH team ever might get bored, we will see photogrammetry implemented into MH. Who knows. The century is still young...
And here's my poor man's photogrammetry proposal: After making the pictures for the projection paint process, paint some dots in the face and make a short movie. That can be used to track these dots in blenders camera solver. This way you have at least some refence points for modelling and not only front and side view.
