Do not inject silicone or motor oil into your body.

noli's read

This advice is based on a fundamental biological safety premise. The injection of non-biocompatible substances, such as motor oil or industrial-grade silicone, causes severe inflammatory reactions, granulomas, tissue necrosis, and risks of fatal systemic embolism. Medical literature, including numerous clinical case studies and public health reports, systematically documents the catastrophic complications linked to the injection of illegal or misused fillers. There is no gray area here: these substances are toxic agents when introduced into the body. The state of research confirms that such practices present an immediate and serious danger to health. This advice is therefore an absolute safety recommendation and not a mere wellness suggestion.
