Name the difference you want to see
Start with your original portrait and finish this sentence: “I want to see what changes if…” You might want slightly more upper-lip fullness, a more defined border, or a different outline at the center of the upper lip. Naming the area gives you a specific place to inspect afterward.
The Cupid’s bow is the central dip and peaks along the upper-lip outline. In a photograph, lipstick, highlights and expression can make that outline look different. A request about its shape should not automatically become a request to enlarge both lips. The preview illustrates an appearance; it does not establish how a real procedure could create it.
Use separate requests for shape and fullness
Fullness only
Explore slightly fuller upper and lower lips. Preserve their current outline, the central upper-lip shape, mouth corners, expression, teeth and lip color.
Border definition only
Make the existing lip border a little clearer without visibly enlarging the lips. Preserve the original outline, mouth opening, expression and color.
Central upper-lip outline
Explore a slightly more defined central dip in the upper-lip outline. Keep the rest of the lip border, overall fullness, lower lip and facial expression consistent with the original.
Pick one brief for the first concept. These are distinct experiments, and none guarantees an exact edit. Read the proposed plan before creating the image. If it combines all three, ask for the single change you intended.
Choose a photograph that shows the border
Use a close, front-facing portrait with a relaxed mouth and even light. The full lip outline and both corners should be visible. Heavy overlining may hide the natural edge; strong gloss may replace the edge with a bright reflection. If those are present, choose another source for a shape comparison.
Do not redraw the original first and then call it your “before.” Keep the source file unchanged so the comparison has a reliable baseline. Our smile and lipstick photo guide explains how mouth position affects what you can compare.
Separate a shape edit from a color effect
Look at the lip edge before judging the whole face. If the lips only became darker, shinier or more sharply outlined by makeup, that does not demonstrate the volume change in your brief. Conversely, a border-only request has gone beyond its scope if the mouth becomes much fuller.
- Follow the central upper-lip outline and both corners.
- Compare upper and lower lip fullness separately.
- Check whether teeth, the mouth opening or the smile moved.
- Inspect the nose and chin for unrelated changes.
Use the same display size for both images. A zoomed-in “after” can make lips appear larger even when their proportions did not change. For a worked volume example, see our lip virtual try-on comparison.
Revise one observation at a time
If the result changed too much, describe the unwanted difference: “The last version enlarged both lips, but I only wanted clearer border definition. Use the original as the reference and preserve fullness.” Review the next plan and the displayed credit cost before generating again.
A model may not preserve every detail, and a visual concept cannot specify an injection amount or treatment plan. Save the original, the concept and your request together. If the issue is a difference between the two sides, start with the one-sided lip preview guide instead of asking for a whole-mouth change.
