The Best AI Prompt for a Double Chin Reduction Look
Use this ChatGPT image-editing prompt to reduce visible under-chin fullness in a portrait while keeping your facial proportions, skin texture, and identity intact.
Edit the uploaded portrait to create a clearly visible, believable reduction in existing under-chin fullness. Use the uploaded image as the source of truth. Where fullness is visible, reduce the rounded bulge beneath the chin and soften the existing under-chin fold so the chin-to-neck transition is more distinct. Make the difference easy to see without making the contour unnaturally tight or hollow. Limit all changes to the under-chin region. Preserve my chin projection, jaw width, bone structure, facial proportions, identity, age, and natural skin texture. Keep my face and the rest of my neck unchanged; do not globally slim either area or redesign my jawline. Retain natural creases and shadows appropriate to the original pose and lighting. Keep my expression, pose, hair, clothing, background, lighting, camera angle, and crop identical. Do not smooth the skin or add other cosmetic edits. If under-chin fullness or a fold is not visible in the source, do not invent it or alter unrelated features. Return one edited portrait. Treat the uploaded image as the source of truth. Do not invent concerns, asymmetries, or features that are not visible. Apply the requested change only where it is relevant and proportionate to what is present. Only refine contours that are visible in the source image. Preserve the person's bone structure, identity, age range, and natural facial proportions rather than inventing a dramatically different jaw or chin.
Upload a portrait with your chin and upper neck clearly visible. The edit will use only contours present in your photo.
For a believable double-chin reduction look, focus the edit beneath the chin rather than slimming the whole face. Upload a portrait with your chin and upper neck clearly visible, then copy the prompt below. It asks for a noticeable, localized contour change while keeping the rest of your photo unchanged.
How to use this prompt
- Open ChatGPT with image editing available and upload a portrait with your chin and upper neck clearly visible.
- Paste the main prompt and request the edit. A three-quarter portrait can make the under-chin contour easier to assess.
- Compare the result with your original at the same size. Check that the change is beneath the chin and that your facial proportions, skin texture, and surroundings remain unchanged.
- If needed, request a targeted revision, such as: “Keep this amount of reduction, but restore the original skin texture and leave my jaw width unchanged. ”
Practical tips
- Use a sharp photo without a scarf, hand, or deep shadow obscuring the under-chin area.
- Ask for a smaller or larger reduction beneath the chin rather than a “slimmer face,” which may change unrelated features.
- If you notice unwanted changes, re-upload the original and repeat the request with a more specific local boundary.
- Choose the subtle variant if you want to retain more of the original fullness and fold.
Prompt variants
Subtle reduction
When you want a restrained adjustment rather than an immediately noticeable contour change.
Edit the uploaded portrait with a subtle reduction in existing under-chin fullness. Slightly reduce the visible bulge and soften any existing under-chin fold, retaining most of the original contour. Change only the under-chin area. Preserve chin projection, jaw width, facial proportions, identity, age, skin texture, and the rest of the neck. Keep the pose, expression, lighting, clothing, background, and crop unchanged. Do not invent fullness or folds that are absent. Return one edited portrait. Treat the uploaded image as the source of truth. Do not invent concerns, asymmetries, or features that are not visible. Apply the requested change only where it is relevant and proportionate to what is present. Only refine contours that are visible in the source image. Preserve the person's bone structure, identity, age range, and natural facial proportions rather than inventing a dramatically different jaw or chin.More defined under-chin contour
When visible fullness is present and you want a more pronounced local edit.
Edit the uploaded portrait to noticeably reduce the existing fullness directly beneath the chin. Make the visible under-chin bulge substantially smaller and soften the existing fold for a clearly more defined chin-to-neck transition, without creating a hollow or unnaturally tight contour. Restrict the change to the under-chin region. Preserve chin projection, jaw width, bone structure, facial proportions, identity, age, natural skin texture, and all other parts of the image. Do not slim the whole face or neck, sharpen the jaw into a new shape, or invent features absent from the source. Return one edited portrait. Treat the uploaded image as the source of truth. Do not invent concerns, asymmetries, or features that are not visible. Apply the requested change only where it is relevant and proportionate to what is present. Only refine contours that are visible in the source image. Preserve the person's bone structure, identity, age range, and natural facial proportions rather than inventing a dramatically different jaw or chin.Side-by-side comparison
When you want to compare the localized edit directly against the original.
Create a side-by-side comparison using the uploaded portrait. Place the untouched original on the left. On the right, use the same photo with a clearly visible, believable reduction in existing under-chin fullness: reduce the visible bulge and soften the existing fold for a more distinct chin-to-neck transition. Change only the under-chin area. Preserve chin projection, jaw width, facial proportions, identity, age, skin texture, pose, expression, clothing, lighting, background, and crop. Do not exaggerate or otherwise alter the original image, globally slim the face or neck, or invent fullness that is not visible. Match panel size and alignment. Add no text. Treat the uploaded image as the source of truth. Do not invent concerns, asymmetries, or features that are not visible. Apply the requested change only where it is relevant and proportionate to what is present. Only refine contours that are visible in the source image. Preserve the person's bone structure, identity, age range, and natural facial proportions rather than inventing a dramatically different jaw or chin.Frequently asked questions
Do I need to upload a photo?
Yes. This prompt edits an existing portrait. Choose a photo with your chin and upper neck visible so the edit can follow the contours already in the image.
Will this change my whole face?
The prompt asks for changes only beneath the chin and explicitly preserves jaw width, chin projection, and facial proportions. Check the result against your original, since image edits can still affect areas you did not request.
What if my photo does not show under-chin fullness?
The prompt tells ChatGPT not to invent it. If the area is hidden by the angle, clothing, or shadows, try another portrait where the contour is easier to see.
Can I use the image to predict a physical change?
No. It is a digital appearance edit, not a reliable prediction of changes from weight loss, a procedure, or any other physical intervention.
