Based on the comments that followed your OP, it's obvious that most of the Afters were to make that actor MORE PHOTOGENIC.
It's clearly not to make someone younger, because many are still young.
The real stumbling block for young actors to get the desired job is the Casting Agents who screen those that apply .... and give a select group to the producers to make a decision from.
There's one top casting agent who routinely told young actors that they should stop wasting peoples' time with going to auditions until they've had their noses "fixed".
Unless an actor is willing to accept only secondary and "character" parts, one major consideration will always be how photogenic are they ... and does the camera "love" them?
