The Substance is a 2024 body-horror film directed by Coralie Fargeat and starring Demi Moore as Elisabeth Sparkle, an ageing television star who takes a black-market serum that creates a younger version of herself. Its electronic score by Raffertie became closely associated with the film's glossy, disturbing tone and spread through short-form edits, trailers and reaction videos. Short excerpts like this one are now reused online to signal transformation, vanity and the darker side of perfection.
