@ChromeStar Now that I take another look at your image I am convinced that it's your shaders. The shaders that Snarly and BagginsBill have set up use a red filter to mask off the eyebrows to they don't get SSS applied to that portion of the map. Your eyebrows have turned red.

This is a good call. Here's the render when I unplug the SSS node from the shader:

The detail is back, and the eyebrow color is back. It's a little hard to see the detail because it's dark, maybe there is too much intensity on the SSS and it's just washing out the detail everywhere on the skin? It's not just the eyebrow (although that's very obvious), but all the freckles and creases are gone too, and turning off SSS fixed that.

This is still the exact same file and settings as used in 11.2, but I'm certainly happier if the difference is an edge case about the SSS node and not handling of textures in general! And masking the eyebrows would be an easy adjustment.

The shader is super simple. There's an image map plugged into diffuse_color, a bump map, an SSS node plugged into alternate_diffuse (with the texture as its input), and a blinn node plugged into alternate_specular (with the red channel from the texture as its input). Could be fancier but it was an old render I redid quickly in superfly.
