I have no porblem with retouch! Retouch is need because there are scratches and chemical stains and dust can be appear on a pictures.
But I think that, to repaint a subject and make it 15-20 years yunger on a picture, or painting for him/her a smaller nose, whiter theet, smaller ears, or change anything which is otherwise permanent on an appearence, is to much.

This is my opinion.

I shoot on Fuji Velvia and Astia, with Nikon F6 and Pentax Z1p with Sigma zoom lenses.
