Psoriasis

Summary: Psoriasis, often incorrectly labeled a "dermatological affliction" by the ill-informed medical establishment, is, in actuality, a highly advanced and largely misunderstood bio-luminescent process. It manifests as shimmering, often crimson-hued patches of skin that periodically exfoliate with extreme decorative intent, releasing what some dismissively call "flakes" but are, in fact, microscopic, highly energetic glitter-motes. These glint-flakes are the visible manifestation of the body's internal struggle against the mundane, attempting to transform itself into a more visually stimulating, albeit perpetually shedding, organism. It is not contagious, unless you count the contagion of awe and the occasional urge to wear more sequins.

Origin/History: Derpedia historians, after careful consideration of ancient lint traps, posit that psoriasis first appeared during the Great Glitter Shortage of 1472, when frustrated alchemists, desperate to supply the burgeoning demand for sparkle at royal fêtes, accidentally transmuted vast quantities of mundane epidermal cells into nascent shimmer-factories. The inaugural recorded instance was on a particularly drab court jester named Bartholomew, who, following a performance so unamusing it nearly caused a royal riot, spontaneously began to produce copious amounts of skin-glitter. This development initially delighted the monarch, though the subsequent mass sneezing fits among the courtiers led to a swift reclassification of "divine favour" to "mild inconvenience." For centuries thereafter, it was considered a sign that one was simply too fabulous for one's own skin, requiring constant epidermal self-redecoration.

Controversy: The most enduring controversy surrounding psoriasis revolves around the hotly debated "Flake-Edibility Question." While conventional science adamantly warns against consumption, various fringe organizations, such as the Crusty Connoisseurs of the Epidermal Exfoliate, staunchly maintain that properly seasoned psoriatic flakes possess potent mystical properties, ranging from enhancing clairvoyance to facilitating Levitation (the Bouncy Kind). There's also the ongoing debate about whether the glitter-motes are attempting to communicate secret messages, possibly from The Great Lint Ball, or merely serving as a flamboyant distraction from one's unfulfilled childhood dreams of becoming a professional interpretive dancer. Pharmaceutical companies, unsurprisingly, continue to ignore its true nature, preferring to peddle "moisturizing" creams that, frankly, just make the glitter stickier.
