# How do I improve face quality?

#### 1. Cause: Differences in model specifications and optimization

* Nano Banana: It has limitations in precisely rendering facial features and skin texture. In particular, image quality degradation becomes more noticeable with repeated edits.
* Flux 2 series (Pro/Max): This model is 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

#### 2-1. Use an upscaler

[26.04.29: Upscaler](/product-docs/product-docs-en/readme-1/26.04.29-upscaler.md)
{% endcontent-ref %}

#### 2-2. Use the Flux 2 model + facial 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 converts it to photorealistic image quality.
