This simple LoRA slider will push the generation toward generating subtle freckles and other skin imperfections to make the skin more realistic and step away from shiny plastic skin. It was made for Chroma-HD.
I made it initially only to create freckled faces, but it turns out that it can be used at lower strength as a super-quick and easy way to fix most plastic skin. Since this is a well known problem most of us has faced before, this LoRA is a simple quick way to solve it - at least partially.
It will not impact the face if you are using a character LoRA.
However, be aware that, like with all LoRA, it will slightly alter your seed, so don't expect 100% exact same generation when using it, obviously.
