How do you fix "Same Face Syndrome"? Changing features still gives me the exact same person.

Hey everyone,

I’m struggling with a massive "Same Face Syndrome" issue in my generations (currently using Seedream 4.5, but it happens everywhere). I'm trying to generate realistic, everyday European/Mediterranean women in their late 30s/early 40s.

Here is my core problem: No matter how much I randomize the facial features in my prompt, I keep getting what feels like the exact same person.

I can prompt for "an aquiline nose," "thin lips," "hooded eyes," or change the hair color completely. The AI does follow these instructions, but it feels like it's just putting different wigs, makeup, and a slightly different prosthetic nose on the exact same base model.

The underlying identity, the bone structure, the proportions, and the "soul" of the face remain identical. It never looks like a genuinely new, different human being. It's just the same woman cosplaying different features.

I've tried using massive, detailed structural prompts (specifying jawlines, cheekbones, eye spacing) and even trying to assign "Identity Signatures," but the AI keeps snapping back to its default clone.

Has anyone successfully broken this? How do you force the engine to generate a fundamentally different person at the base level, rather than just changing the Mr. Potato Head pieces on the same default face? Any prompt formulas or specific keywords would be a lifesaver.
