How do I improve facial image quality?

If the model's face is blurry or distorted, please check the information below.

1. Cause: Differences in model-specific specifications and optimization

• Nano Banana: It has limitations in precisely expressing a person's facial features and skin texture. In particular, the more times it is edited, the more noticeable the drop in image quality becomes.

• Flux 2 series (Pro/Max): This is a model optimized for generating high-resolution photorealistic images. With billions of parameters, it delicately depicts a person's eyes, eyelashes, and even skin pores.

2. Solution: Use the Flux 2 model + face quality enhancement prompts

After switching the model to Flux 2 Pro or Max, try adding the following 'face detail-related keywords' to your prompt. The Flux 2 engine removes the AI-like feel when describing "skin texture" and "the depth of the eyes," and shifts to photorealistic image quality.

Editing goal	Recommended prompt (Copy & Paste)
Enhance face detail (crisp editorial look)	Hyper-realistic skin texture with visible fine pores and natural imperfections, avoiding any airbrushed look, super-sharp focus on the eyes with clear catchlights, deep contrast and cinematic clarity in facial features, high-fidelity 8k resolution.
Maximize natural facial sheen (natural feel)	Facial features rendered with extreme clarity, showcasing authentic skin luster and natural fine textures, diffused and soft lighting effects across the face to ensure a lifelike look, high-definition resolution without over-processing.
