How do I create AI images that don't have messed up hands and faces?

To fix AI-generated hands and faces, use negative prompts to exclude common deformities and switch to a model specifically fine-tuned for anatomy, like SDXL with a detailer extension. This problem has been the running joke of AI art since 2022. Fingers that look like melted candles. Eyes pointing in different directions. The reason it happens is that hands are incredibly complex — 27 bones, countless positions — and the training data is full of low-resolution images where hands are just a blur. The AI never learned what a correct hand actually looks like. Here's a concrete workflow that works. In Midjourney, add '--no extra fingers, fused fingers, distorted hands, bad anatomy' to the end of your prompt. Then crank up the stylize setting to around 700. That alone cuts the mutation rate in half. For Stable Diffusion users, install the ADetailer extension. After the image generates, ADetailer automatically detects faces and hands, then re-renders just those areas at higher resolution with a model trained on close-up portraits. I've used this on dozens of character portraits and it's not perfect, but it's dramatically better. One tip nobody mentions: if you're generating a full-body shot, make sure the hands are near the face or holding something simple. AI handles hands in pockets or behind backs much better than intricate finger poses. If you absolutely need a specific hand gesture, generate the image without it, then use inpainting to add the hands separately. It's extra work, but it beats getting a six-fingered nightmare. **Related**: Which AI image generator is best for realistic portraits? | How do I write better Midjourney prompts for consistent characters?
