This Lora can generate a wet skin with a strong gloss.

.

Trained only with realistic images.

Surprisingly, the results were good enough to be used for 2D illustrations.

Recommended strength : 0.6-1.0
Trigger Words : shiny skin,
if you want more shiny skin : oiled,

I'm not familiar with photorealistic images so I don't know if this Lora works well.
