FluxLora trained on a lot of closeups of faces, skin portraits, blemishes, freckles etc.
This version is 12 epochs, there's up to 20 epochs but the effect becomes too strong at those higher epochs.
Trained on civitai's trainer for fun.
Attached are some comparisons and images with workflow + prompts etc included.

Usage:
I recommend running through flux CFG guidance of 2 to 2.5
I went 20 steps and same seed for consistency in examples but a variety of steps between 20-40 works well.

Workflow is embedded for comfyui in the examples also
