The Best AI Prompt for a Masseter Botox Look

Want to explore a masseter Botox–inspired look in a photo? Upload a clear, front-facing portrait with both jaw angles visible and your face relaxed. This prompt focuses on the outer lower cheeks and jaw angles rather than slimming your entire face. The result is a cosmetic visualization, not a prediction of how a treatment would affect you.

How to use this prompt

• Open ChatGPT with image editing available and upload a clear portrait taken straight on, with a relaxed expression and both jaw angles visible.
• Paste the main prompt and send it with the uploaded portrait.
• Compare the outer lower cheeks and jaw angles in the two versions. Check that the chin, upper face, expression, and skin texture remain unchanged.
• If you want a different intensity or output format, use one of the variants below with the original portrait.

Practical tips

• Choose a photo without a beauty filter so the edit starts from your actual facial contours and skin texture.
• Keep hair away from both jaw angles. Covered contours give the model less reliable information to work with.
• Use a straight-on photo rather than a wide-angle selfie taken from above or below.
• If the edit changes your chin or cheekbones, ask: “Restore those features from the original and change only the lateral fullness near the rear lower cheeks and jaw angles. ”
• A jaw that already has little visible lateral fullness may show a smaller difference. Avoid asking the model to manufacture a broader starting face.

Prompt variants

Subtle contour change

Choose this when you want a restrained comparison rather than an obvious contour change.

Use the uploaded portrait to create a subtle masseter Botox–inspired cosmetic visualization. Where visible, slightly reduce outward fullness at the rear lower cheeks and jaw angles. Keep the change deliberately understated, and do not invent fullness that is not present. Preserve my identity, chin width and position, underlying jaw character, cheekbones, facial features, expression, natural asymmetry, skin texture, age cues, hair, clothing, lighting, framing, and background. Do not slim the whole face or add other retouching. Return the original unchanged on the left and the edited portrait on the right at matching scale. This is an aesthetic illustration, not a prediction of treatment results.

More pronounced localized narrowing

Choose this to explore a stronger localized change when your portrait shows visible fullness near the jaw angles.

Edit the uploaded portrait to show a more pronounced masseter Botox–inspired lower-face contour. Where outward fullness is visible, substantially reduce its lateral projection at both rear lower cheeks and jaw angles so the narrowing is unmistakable. Keep the result plausible for my face, without inventing fullness or changing other areas to amplify the difference. Preserve my identity, chin width and position, underlying jaw character, cheekbones, facial features, expression, skin texture, age cues, natural asymmetry, hair, clothing, lighting, framing, and background. Avoid a pointed chin, global slimming, or beauty retouching. Return a matched side-by-side comparison with the unchanged original on the left. This is a cosmetic visualization, not a treatment prediction.

Single edited portrait

Choose this when you want a standalone portrait instead of a side-by-side comparison.

Edit the uploaded portrait to create a masseter Botox–inspired cosmetic visualization and return only the edited image. Where visible, reduce outward fullness at the rear lower cheeks and jaw angles enough to produce a clearly narrower lateral lower-face contour. Do not invent fullness that is absent or slim other parts of the face. Preserve my identity, chin width and position, underlying jaw character, cheekbones, facial features, expression, natural asymmetry, skin texture, age cues, hair, clothing, lighting, framing, and background. Make no unrelated changes. Keep the original image dimensions and crop. The result is an aesthetic illustration, not a prediction of treatment results.

Frequently asked questions

Do I need to upload a photo?

Yes. The prompt uses your portrait to preserve your features and make a localized edit. A clear, front-facing image with a relaxed expression and both jaw angles visible works best.

Can this show what Botox would actually do to my face?

No. An AI edit changes pixels; it cannot assess your anatomy or predict your response to treatment. Use the image to explore an aesthetic preference, not to make a medical decision.

Will the prompt change my chin or slim my whole face?

It specifically asks ChatGPT to preserve your chin and other facial features while changing only visible lateral fullness near the rear lower cheeks and jaw angles. Check the output, since image edits can still introduce unintended changes.

What if my jaw already looks narrow?

The prompt tells ChatGPT not to invent fullness or alter unrelated features to create a larger difference. A portrait with little visible fullness in the target area may show only a small change.
