StretchMark - Stretch Marks Concept LoRA [Illustrious/SDXL]

Trigger words: stretchmark

Because no body is perfect.

Adds natural stretch marks to your characters - the kind of subtle skin detail that makes a body feel real and lived-in. Marks appear where they naturally would: inner thighs, hips, lower belly, butt, and breasts.

The LoRA supports two modes depending on how you prompt:

WHITE/HEALED MODE (recommended): Add "subtle white stretch marks, faint silvery lines on skin" to your positive prompt and "red_skin, rash, redness" to negative. Gives you soft, silvery-white lines that look elegant and natural.

FRESH/NATURAL MODE: Just use the trigger word without color guidance. You get pinkish marks like newer stretch marks.

Works beautifully with curvy body types - thick_thighs, wide_hips, large_breasts, plump, BBW all pair great with this. But it works on any body type.

PRESETS:

Lite (str 0.4-0.6): Very subtle, barely-there marks. A hint of realism without drawing attention.

Standard (str 0.8): Clear, visible marks with natural placement. Start here.

Full (str 1.0): Bold, prominent marks with wide coverage.

TIPS:

- Use "stretchmark" trigger word in your prompt

- Add body part tags (thighs, hips, ass, belly) to guide placement

- "close-up" and "from_behind" angles show marks best

- Works with any art style - tested with oil painting, watercolor, charcoal, ukiyo-e, and more
