I can't PS , so I don't have full appreciation of the explanation. I do appreciate you posting to show how it is done.
I often seen the "How-to improve Portrait Photography" articles with all the smoothing and blending. I find the portrait loses the personality - & always appreciate the person's character before fixing the" flaws".
Everyone wants to look better, but it would feel rather insulting to know that the photographer felt the need to change you.
But we are just "people" , & hey - that's Hollywood.
I also know that any Painter with a lick of sense would soften certain details - in order for the subject to truly it. Blame it on the brushes.
Shame, the expectations that we have.
EDIT - Oh, that reminds me of some of the Realtor Glamour shots. Seriously, what are you selling here...
