When using the facial recovery process, it frequently does not cover things like a neckline into the clothing. This leaves a very obvious quality difference in the skin which can be rather unpleasant.
I have also thought about this, retouching software such as PortraitPro Studio Max for example allow adjusting, it would be nice to have this.
We’re working on improving the Face Recovery models to not have such a stark contrast with the rest of the body. In the meantime, try turning down the strength of the model and turn on/up the Upscale model which will enhance the resolution of the entire image.
