Help with matching skin tones

[Lankanion]

Hope someone out there can help me with this. I have a number of photos to retouch and balance skin toning. The basic problem is that the young lady in the photographs has two distingt skin tones but no clearly defined 'tan line'. The differences are detectable and visible (between her back and backside for instance) and I guess caused purely by sun exposure pigmentation versus those bits that never see the sun!!

I'm hoping that someone has a quick fix solution. I've looked at various methods but they all seem extremely complicated and most seem to require some way of selecting the line betwwen the varioius tones. I dont have anything, more of a gradual change from pink to white.

Thanks in advance

Try painting with the history brush on a multiply layer for making the lighter area darker, or on screen layer to make the darker area lighter. You will probably have to play with opacity and a little blur.

You might try selecting the area to be darkened with color range and then jumping or copying that to a multiply layer. That might leave some weird edges that you'd have to heal or clone out.
