Awwww, jeez... Nuthin' like a li'l
pressure!
(Thank ya, Danny for the compliment - now if I can only live up to it...

)
Okaaaaayyyyyyy, here's what I did:
Selected the area with the magic wand tool (set to 30/Not contiguous)
Hit quick mask, refined the selection with the paintbrush and blurred the selection, exited quick mask
Desaturated selected area
Chose skin color with the eyedropper, made a new layer, filled selected area @ 100% and set layer to Multiply
Contracted my selection and did the fill/multiply thing again (on another layer)
Repeated one more time
Flattened
Made a new layer and blended it all together by painting. Also painted in shadows on sides of nose.
Added noise to the paint layer and flattened
I didn't fix all of the discoloration, but you get the idea...
