Best way to do human skin for a model that will be used for web in GLB format?

Hey! I have a human model that I have put together for a Three.js web app. The model will be a GLTF/GLB file and will ultimately be compressed with Draco.

I’m at the point where I am creating the skin material and wanted to come and ask the pros for some tips!

I’m looking for some pointers on the best way to create skin material (for a black person if that matters) that would be good for performance and file size?

I’ve been researching on my own, have set up some skin shaders, and considered using a texture map, but need help figuring out what the best overall move would be for my specific use case.

Thank you!!
