Very basic workflow for generating what I think are high-quality ZIT 1girl photos.
Very simple T2I using ZIT (basically the template), upscale with SeedVR2 (basically the template), then face detail with ZIT (I'll try to add different versions, but my default uses SAM2 for face detection and inpaint crop and stitch instead of the face detailer node).
SAM2 - adjust the threshold as needed
Face detail - adjust the denoise and steps as needed

i really like this! but for some reason, every once in a while, people come out looking sweaty.
I found that having "swimwear" or similar in the prompt can result in a wet skin look.
The face detail step can sometimes add "sweat" looking artifacts, weirdly increasing the CFG seems to help with that, or decreasing the denoise.
@BottleForkBerry77 i'll tinker with that! right now i'm just re-running the ones that come out that way, it only takes a few more seconds, and the change in the seed is enough to fix it, i moved the detailer to a separate batch workflow so i can work with the same base image more than once if i have to
I did some tinkering and I think I found a slight modification to your workflow that considerably reduces the sweaty results but keeps good detail. i'm doing a face detail at 0.40 denoise prior to the seedvr upscale, and then another one at 0.20 denoise after the upscale, using the same prompt. the initial denoise gets the bigger detail changes at the smaller size and the second denoise does minor fine adjustment after the upscale. it takes a little longer but the results are about the same as with 0.30 in one pass, but without the sweatiness. under the original settings I was getting sweatiness about 25% of the time, now it's only about 5%, and when I do get it, it's more subtle!
i think i figured it out! when the mask/crop node upscales, it's introducing errors, basically single pixels of white or near-white color, and the sampler is sometimes reading those as "wet spots" (but sometimes reading them as "sparkles"). i switched to lanczos for upscaling and downscaling and it's happening less frequently. probably no way to get rid of it entirely and it probably depends a lot on how much you have to upscale the crop. but it's definitely happening before the stitch because if you preview right behind the sampler you'll see the "wet spots" even before the crop gets stitched back in
