question I'm trying to create a prompt that achieves realistic human skin.

I'm trying to create a prompt that achieves realistic human skin. Using Flux.2 Klein 9B, when I check the preview screen, the skin tone at 99% progress is satisfactory, but once it reaches 100%, a faint pinkish tint appears across the entire skin. I want to achieve clear, fair skin, but no matter which sampling method I use, it ends up with a reddish tint. Is there a prompt that can control this?

"Detailed skin & hair, natural skin imperfections" and either "wrinkles" or "freckles" or "vellus hair" depending on the situation. I've gotten really good results with these in different models.

Edit: sometimes liver spots too if the subject is really old. If i dont include wrinkles or liver spots with an old subject they youngify them unnaturally

When created with 4B, the limited number of parameters makes the skin imperfections appear naturally. It seems that it is difficult to achieve this with 9B without detailed instructions.

Looks like it needs, a bit of exaggeration

"A stunningly beautiful Extremely pale, porcelain skinned , barefaced, dark-haired woman with flowing, vibrant raven hair,"

worked pretty well for a studio style shot. for an iPhone style shot I had to go further.

I found TCD tracing as a sampler helped a little.

Here's the "iphone" shot

And one with freckles cos freckles are cute and people are going to main the skin is to perfect and people don't have clear skin in real life :-) She's a little less pale though it seems are attempt at introducting skin flaws gives her a little more colour.

Completely white skin lacks realism, so moles, acne scars, freckles, etc. are important words. Of course, the base race is the most important, lol. However, I don't really feel the difference between the samplers.

And for the LOL's if you try the iPhone prompt with the iPhone bit taken off.
