It is a by-product of overfitting. I found the model I trained recently is always so shiny, I think some of you may like this style.

It doesn´t need any prompts, but you can add shiny skin as positive prompt.

Only need to apply the LoRA by <lora:shinyskin:0.8>, for example.

Compare with shiny skin generated by default, it is a little shinier and more saturated.

And if applied in realistic model like chilloutmix, it is somehow different, the chin will become slightly (or strong, depends on weight) pointed and the character will be anime oriented.
