The odd thing about all this is that there is a huge industry which is based upon Photoshopping faces to get rid of wrinkles, smoothen the skin, make the eyes brighter etc etc. Also there are probably as many people who want to be professional retouchers as there are aspiring models.
I guess there is a demand for the Barbie retouch so a lot of retouchers will spend hours getting rid of all skin imperfections.
