The Best AI Prompt for a Slimmer Face Look

Upload the portrait you want to edit, then copy the prompt below into ChatGPT. It focuses on the cheek and lower-face outline for a clearly visible change without altering your body, smoothing your skin, or changing the rest of the photo.

How to use this prompt

• Open ChatGPT with image editing available and upload the portrait you want to change.
• Paste the main prompt and send it with the image.
• Compare the result with your original, checking the cheek and lower-face outline as well as your expression, skin texture, and background.
• If needed, request a focused revision such as: “Reduce the narrowing slightly, keep my original chin shape, and leave everything else unchanged. ”

Practical tips

• Use a sharp portrait with the face unobstructed. A front-facing view makes changes to face width easier to judge.
• Choose a photo without a heavy beauty filter so the edit can retain the original skin texture.
• If one part of your face should stay exactly as it is, name it explicitly—for example, “Keep my cheekbones and chin unchanged. ”
• Inspect hair edges, earrings, and background lines near the face for bending or distortion.
• For revisions, attach the original again and describe the desired change relative to it to reduce accumulated alterations.

Prompt variants

Subtle contour adjustment

Choose this when you want a small adjustment rather than an immediately noticeable change.

Edit the uploaded portrait for a subtle slimmer-face look. Use the original as the source of truth. Where visible, slightly reduce lateral cheek fullness and lower-face width, keeping the change understated and the facial proportions believable. Do not invent fullness or reshape features that are already narrow. Preserve identity, expression, eyes, nose, lips, chin shape, skin texture, age cues, hair, neck, body, clothing, background, framing, and lighting. Make no other changes. Return one edited portrait.

Lower-face focus

Choose this when you want to adjust the lower-face outline without reducing the cheeks.

Edit the uploaded portrait to create a visibly narrower lower-face outline where width is present. Keep the cheeks and cheekbones unchanged, and preserve the chin's existing shape rather than making it pointed. Use the uploaded image as the source of truth; do not invent width or asymmetry. Keep the person recognizable and retain their expression, eyes, nose, lips, skin texture, age cues, hair, ears, neck, body, clothing, background, framing, and lighting. Limit all changes to the lower-face contour, with natural transitions and no warped surroundings. Return one edited portrait.

Side-by-side comparison

Choose this to compare the localized edit with your unchanged original in one image.

Create a side-by-side comparison using the uploaded portrait. On the left, place the original photo completely unchanged. On the right, place the same portrait with a clearly visible, realistic slimmer-face edit: reduce lateral cheek fullness and lower-face width only where present. Do not add or exaggerate any feature in the original to increase contrast. Preserve identity, expression, eyes, nose, lips, skin texture, age cues, hairstyle, neck, body, clothing, background, lighting, and crop. Keep facial proportions believable and avoid a pointed chin or hollow cheeks. Match both panels in size and alignment. Add no text.

Frequently asked questions

Do I need to upload a photo?

Yes. Upload the portrait you want to edit before sending the prompt so ChatGPT can work from your actual facial features and surroundings.

Will the prompt change my body or skin?

The prompt asks for changes only to the cheek and lower-face outline, while preserving your body and skin texture. Check the result against the original and ask for a correction if anything else changes.

What if my face is already narrow?

The prompt tells ChatGPT not to invent fullness or exaggerate narrowing. You can use the subtle variant or specify one small contour adjustment you want to see.

How can I avoid a pointed chin or an unnatural result?

Ask ChatGPT to retain your original chin shape and reduce the strength of the narrowing. Keep the original photo attached when requesting the revision.

Does this show what weight loss would look like?

No. It is a localized photo edit, not a prediction of how your face would change with weight loss.
