There are plugins for Photoshop out there specifically for skin correction. I do not know if they are actionable though. At the moment the names escape me.
But I think that the better idea here, as mentioned above is to not have to do as much after the shot as you are now. Make sure that the camera is set properly. If you are using camera raw, you can "build" your own profile for the camera that will work most of the time. there is also a free "setup" for camera raw that someone has mad that automates doing this and is extremely successful with just about all of your shots. Or if you are really serious about photography, Integrated Color, a phenomenal software company dealing with color management, has a great program to build a real profile for your camera that nearly guarantees a perfect shot all of the time. It is not terribly cheap but not real expensive either and it really does work. I have used it t calibrate a lot of my clients cameras for their shoots and loaded the profile into Capture One. Really nice results.
