Short description of error
With EEVEE, If Subsurface Scattering enabled, Mix shader didn't MIX subsurface scattering materials. Maybe it ADDs materials.

Exact steps for others to reproduce the error

Try this .blend file with blender 2.80 beta newer than 25/Apr build. Render with EEVEE renderer.

SSS mix shader still behaves strange, it creates banding. You can notice it better if mix factor set at zero. sss_2.blend
