Why isn't SSS rendering properly for me?

Sub Surface Scattering isn’t rendering properly for me. I have tried almost everything from changing the shader to remaking the entire model

. As you can see, it weirdly brightens up the model. It’s renders fine without SSS. I just can’t figure out how to render out the SSS. I have baked a thickness map and inverted that map for the SSS and it should render out without any problems. Any Help will Really be appreciated.
