Many users have noticed that while generating photos using Gemini, the face often changes from image to image, even when the same reference photo is used. This inconsistency can be frustrating, especially for creators who want realistic and accurate AI-generated portraits. However, a simple hidden setting inside the Gemini app can permanently fix this issue.
By adding a specific instruction inside Gemini’s personal settings, users can lock their facial structure so Gemini no longer alters their face during image generation. Once enabled, Gemini prioritizes the facial features from the reference image and maintains the same identity across all future photos, while only adjusting pose, lighting, and background.
To activate this feature, users need to open the Gemini app and tap on their profile icon. From there, navigate to Personal Controls and then open the “Your instructions for Gemini” section. After tapping the add button, paste the facial consistency prompt exactly as provided, without making any changes.
This instruction forces Gemini to maintain strict facial consistency, ensuring that the core facial structure remains unchanged in every generated image. The AI adapts only non-identity elements such as angles, lighting conditions, and environment, while preserving the original face accurately.
Prompt to paste:
Enable strict facial consistency mode. Prioritize the facial features from the provided reference image for all subsequent generations. Maintain the subject’s identity accurately while only adapting the pose, lighting, and background. Do not alter the core facial structure.
Users who have tested this method report generating multiple images without experiencing even a single facial change. This makes the trick extremely useful for content creators, influencers, and anyone using AI-generated photos for personal branding or professional use.
This simple yet powerful tweak turns Gemini into a reliable tool for realistic and consistent AI portraits. If you are tired of seeing your face change in every generated image, this hidden prompt is something you should enable immediately.
