Fresnel/IOR Blender 3

I have Blender 3.0.0 and in PBSDF there is a "subsurface IOR".  Should i change the IOR with this one or with specular value, as mentioned in this course.

Thank you very much

    I would stick with using the specular value. The Subsurface IOR will only affect the scattering that's happening under the surface when using SSS, but the specular is affecting the surface regardless.
