With Fix

Deviation and change from original settings to improve quality:

LMS Fix

PLMS (20 steps)

PLMS (50 steps)

Since this is a small issue, inpainting can be used to remove the specs on the faceBut from further tests, simply increasing the sampling steps should be sufficient

DPM fast Fix

Requires at least 50+ Sampling steps to get a cohesive image, but even so the image is not as good as using the other samplers

DPM fast

DPM fast (Sampling Steps 50)

PLMS Fix

PLMS

PLMS (Sampling Steps 50)

Alternatively, you can use face fix to fix the PLMS image, but sampling steps solve the problem pretty well.
