The number one complaint about AI photo editing is simple: "The photo is nice, but that is not my face."
It happens to everyone at first. The AI sees your photo, gets a rough idea of you, and then invents a new, slightly different person. The good news is that this is fixable. Face change is not random bad luck. It comes from specific causes, and each one has a fix.
Why AI changes your face
The AI does not store your face like a photo file. It reads your picture, turns it into a description, and rebuilds a face from that description. Every rebuild loses some detail. The stronger the style change you ask for, the more the AI rebuilds, and the more your face drifts.
So the game is simple: ask for the change you want, and protect the face while you do it. Here is how.
1. Use identity lock wording
The strongest tool you have is one clear sentence near the top of the prompt. The prompts on Faymas are written with this built in. The wording looks like this:
"Preserve his exact facial identity from the uploaded photo. 100% face match. Do not change the face shape, eyes, nose, lips, jawline, or skin tone."
That sentence tells the AI the face is not part of the edit. Change the clothes, change the place, change the light, but the face is locked. If you ever write your own prompt or adjust one, keep this line in and keep it near the top. Instructions at the top carry more weight.
2. Give the AI a face it can read
Your upload matters as much as the prompt. The AI locks onto what it can see clearly.
- Face big in the frame. A selfie or a half-body shot works best.
- Face straight or nearly straight to the camera.
- Bright, even light. Daylight from a window is perfect.
- No filters, no skin smoothing, no portrait-mode blur on the face.
- Eyes open and visible. Sunglasses break identity lock almost every time.
A small, dark face in a group photo gives the AI almost nothing to hold on to. It will guess. And its guess will not be you.
3. Change one big thing at a time
Asking for a new outfit, a new city, a new hairstyle, and a movie-poster style in one go forces the AI to rebuild everything at once. Your face gets rebuilt along with the rest.
Work in steps instead:
- First generation: change the outfit only, keep the background plain
- Second generation: take that result and change the background
- Third generation: adjust light or style
Each step is a smaller rebuild, so the face survives. This takes a few extra minutes and saves a lot of frustration.
4. Avoid style words that fight the lock
Some words push the AI to invent a new person: "model face," "handsome man," "beautiful woman," "perfect features." The moment the prompt describes an ideal face, the AI starts swapping yours for that ideal.
Faymas prompts avoid those words on purpose. If you edit a prompt yourself, describe the clothes, the place, and the light in detail, and describe the face not at all. Locked and undescribed beats described every time.
5. Regenerate before you rewrite
Even with a perfect prompt and photo, one generation can come out wrong. The AI samples a new result every time. If the style is right but the face drifted, hit regenerate with the exact same prompt and photo before you change anything. The second or third try often locks in.
6. Know the hard cases
Some photos are simply hard for today's tools:
- Childhood photos turned into adult portraits
- Side profiles turned to face the camera
- Very old or low-resolution photos
- Photos where two people stand close together
These can still work, but expect more tries. For couples prompts, use a photo where both faces are clear and not overlapping.
A quick test for any result
Zoom in. Cover the clothes and background with your hand and look only at the face. Would your mother recognize you in one second? If yes, the lock held. If you have to convince yourself, regenerate.
Your face is the whole point of these prompts. The style is just the frame around it. Protect the face first, and the rest falls into place.
