Img2img+face detailer workflow(Flux/Illustrious),and you can compare the result before/after the face refine.I tested with several checkpoints,this workflow fits better with:

For flux dev version:
Edge of Reality 真实边缘 - 3.2 Beyond Reality | Flux Checkpoint | Civitai

For illustrious version:

Vauxz Merge 2.5D - 3D - ILLU v.Sarah | Illustrious Checkpoint | Civitai
