Going to a make-up artist would help by asking how it's applied to a face. And apply that knowledge in digital form. It would even be better to go to a make-up artist that their speciality is in corrective make-up tech's. "Make-up artists" that work with photographers in the fashion field. Where using the corrective tech's for film(pictures),digital work. These techniques are applied not only for correcting narrow lips,one eye slightly smaller than the other on those models(and for people) that are only 99% perfect(take that with a grain of salt). But for the lighting that photographer is using. Sometimes, it's flat lit(no shadows) 1 to 1 ratio. So the "corrective" tech. helps in making the face "appear" with contour. Talking more down to earth. To appear using a (corrective) lighting technique in photography that a photographer would use for portraits on people.....Short loop, Butterfly,broad lighting........But it's not the same thing. .......Sliming down or narrowing down the face and/or nose features. And that's what the corrective make-technique does for noses,the face,cheeks. As I remember, make-up artists call it highlighting and shadowing. They make the bridge of the nose lighter than the sides,which are darker. As I'm told from these make-up artists it's easier in P.S. The liquify command can do a lot of that work for you and using those basic make-up techniques.
Then there's make-up artists like "Joe Blasco". Not only does he do "regular" make-up but also special effects. He use to have a make-up(I forget what it was called) it was a heavy make-up.....Like most of his make-up line is. You have to go light on it......A little goes a long way.Had some kind of metal in it. It was white, and the oldtimers(photographers) used it for B&W photography. The models "appeared" like porcelin dolls. It was that heavy. This stuff could be used for fixing impact damage to automoblies I remenber...... It had to be applied every.......like 15 min. under "hot lights". It just saged. That "looked" real good ! Had to be their !
So getting some shots on film,digital and looking at the texture and technique of the make-up helps as well.
