The acid that banished the shadow of the sun, nicotinic acid, carried a name derived from the harsh chemical oxidation of nicotine itself. A paradox of health built from the shadow of poison. Its absence in the early 20th century carved deep, angry lesions across the skin of the American South—pellagra's signature. That raw dermatitis, often mistaken for mere sunburn, necessitated the stark intervention of a B vitamin, forcing the medical community to look past topical salves and into the cellular structure of nutritional deficiency.
Before refined creams, the pursuit of dermal flexibility often involved the meticulous processing of unique animal byproducts. Consider isinglass. Not a glass, but a purified form of collagen harvested specifically from the dried swim bladders of certain fish, especially the beluga sturgeon native to the Caspian Sea. This translucent material held immense value, employed not for application to the face, but as a superior clarifying agent—a fining agent—pulled through murky beer and wine to capture minute particulates, rendering a beverage perfectly clear. Its adhesive properties were unparalleled for specific repairs; a necessary, translucent adhesive.
Vellum, too, stands as a testament to the enduring structural power of collagen fibers. Prepared from calf or goat skin, meticulously stretched and scraped thin, the process eliminates nearly all components except the pristine collagen matrix. This was not skincare, but an archival material engineered to resist the wear of centuries. Fourteenth-century mapmakers relied upon this extremely purified animal protein to chart the stars, knowing the skin would not crack or degrade. It demanded patience. Months of curing the membrane to achieve that signature tensile strength and brilliant white surface for illuminated manuscripts. A durable, highly elastic sheet of pure protein, repurposed entirely.
