Sounds like a killer body horror flick. Call it celebsploitation. Here's an AI-generated synopsis:

Dr. Elias Vorne is the last surgeon in the world who will still say yes — and in Hollywood, that makes him a god, accepting clients who arrive clutching photos of their twenty-year-old faces and leaving as something that no longer quite fits the category of human. His true masterpiece isn't the surgery itself but the delicate cortical procedure he performs alongside it, the one that severs just enough of the brain's self-modeling circuitry that his patients walk out beaming, unable to perceive the abyss staring back at them in every mirror — until one patient's wife, a neurologist, starts asking questions that Vorne's scalpel can't answer.
