There are quite appropriate uses for other PS tools as well.  I blur my face and remove tattoos (using a variety of tools) for privacy, with a disclaimer stating they exist on my gallery page.  I've also used the perspective tool to fix distortion caused by shooting up or down angles (stairs, etc.).  Oh yeah, and I've been known to remove a zit from my butt, remove a crease on my belly from not sitting up straight, and lighten the shadows cast on my face...  

Seriously, some photo editing makes the pics look more representative of what you will actually see in person.

No doubt it is wrong to use outdated or deceivingly altered photos.  That said, can we consider getting more realistic with the phrase "model material" ?  Most people do NOT have a pro make up artist and light designer with them during sessions... I think society has forgotten what real people actually look like.

I only ever edit lighting and have plenty of selfies on my site so you know exactly what you're getting into.
