Stable Diffusion Prompts for Facial Expressions

Generating realistic and detailed facial expressions in AI-generated portraits can be challenging. However, with the right stable diffusion prompts and techniques, you can create portraits conveying a wide range of emotions and moods.

Emotion and Expression Keywords

The key to generating expressive faces is using targeted emotion and expression keywords in your prompts. Here are some examples:

  • Joyful, ecstatic, blissful, delighted
  • Sad, mournful, devastated, crying
  • Angry, enraged, furious, screaming
  • Fearful, terrified, panicked, screaming
  • Disgusted, repulsed, nauseated, cringing
  • Surprised, shocked, astonished, jaw dropped
  • Trusting, loving, affectionate, smiling

Combine these with adverbs and adjectives to refine the intensity of the expression:

  • Slightly smiling, subtly frowning
  • Beaming joyfully, bawling uncontrollably

Directing Gaze and Gestures

Facial expressions don’t just involve the face. The direction of gaze and positioning of the head, shoulders and hands can completely transform an expression.

Use keywords to direct these aspects:

  • Eyes downcast, gazing upward
  • Head tilted, turned away
  • Hand covering mouth, finger pointing

And don’t forget full body gestures:

  • Jumping for joy, stomping angrily
  • Slumped over sobbing, screaming fearfully

Enhancing Realism

The most realistic facial expressions showcase fine details like wrinkles, flushed skin, wet eyes, facial muscles, and more.

Prompt stable diffusion to generate these realism cues:

  • Forehead wrinkled, jaw clenched
  • Reddened complexion, veins protruding
  • Wet eyes, tears streaming down cheeks
  • Fine lines around eyes and mouth

Take care not to overdo it though, as too much emphasis on small details can make the overall face seem less coherent. Strike a balance between realism cues and a harmonious whole.

Direct Manipulation

You can directly manipulate facial features and expressions using special prompts like:

  • ((add tears running down both cheeks))
  • ((make mouth open wide showing upper and lower teeth))
  • ((make eyebrows lowered and together))

This level of control takes practice, but allows precise fine-tuning. Refer to facial anatomy diagrams to identify the names for individual facial muscles and features.

Compositing Expressions

Blended expressions can heighten realism and emotional impact. For example:

  • 50% ecstatic, 50% affectionate
  • 75% enraged, 25% disgusted

This compositing works for gestures and gazes too:

  • Looking left while pointing right

Mix things up, but ensure the combined expressions make logical sense emotionally and physically.

Example Expressions

Here are a few full prompt examples for generating expressive portraits with stable diffusion:

Portrait of a senior man, looking directly at the viewer, face wrinkled and red, eyes wet with large tears streaming down both cheeks, mouth open wide showing upper and lower teeth, hands clutching head, devastated and bawling uncontrollably

Teenage girl outside leaning against brick wall, head tilted slightly, gazing upward, sunset lighting, feeling 75% blissful 25% trusting, eyes glistening, subtly smiling

Toddler boy playing in pile of autumn leaves, jumping playfully, leaves flying, beaming joyfully, looking at viewer, morning side lighting

Follow these guidelines and keep experimenting until you find prompts that produce portraits conveying the precise mood and emotion you desire!

Advanced Expression Control with E4E and GFPGAN

For even more control over facial expressions, make use of state-of-the-art tools like E4E (Editing for Expression) and GFPGAN.


With E4E, you can literally sculpt any facial expression and have it realistically rendered onto a portrait.

To use E4E:

This enables unparalleled control over every minute facial detail.


GFPGAN is a tool for editing portrait images and video in real-time. Among many features, it allows animated facial expression transfer.

You can take a short video clip of someone making a facial expression, and transfer this expression onto a Stable Diffusion generated portrait.

The possibilities are endless – imagine transferring the facial expressions of old film actors, funny internet clips, or personal iPhone videos onto AI-generated portraits!


With the right prompts and tools like E4E and GFPGAN, Stable Diffusion gives you immense control and flexibility for showcasing emotions through highly realistic facial expressions.

Experiment with emotion keywords, compositing expressions, directing gaze and gestures, enhancing realism cues, and leveraging state-of-the-art editing tools.
