Clinuvel distributes a single product, Scenesse, the only approved treatment for phototoxic reactions specifically associated with a rare genetic disease called erythropoietic protoporphyria. EPP causes extreme pain or burns from brief exposure to light, affecting a patient’s quality of life. Scenesse is a patented dissolvable implant, comparable in size with a rice grain, injected underneath the skin roughly every three months for ongoing protection. The implant controls the release of a synthetic drug which promotes the production of more melanin, thereby reducing pain and increasing tolerance for light exposure. The majority of Clinuvel’s earnings stem from Europe and the US.
