SHORT PITCH (AS SOLD)
Take a small daily wafer and grow slender and clear-skinned. Arsenic stimulates the system, carries off surplus flesh, and refines the complexion, with no effort and (so the advertisements said) no danger.
THE ACTUAL EVIDENCE
Arsenic is a cumulative metabolic poison and a recognised human carcinogen (IARC Group 1); it is not a safe slimming or beauty aid. Any short-term cosmetic impression came at the cost of chronic arsenical exposure, and habitual users risked skin lesions, neuropathy, organ damage, and cancers. No controlled evidence ever supported a safe slimming or complexion benefit. The claim is refuted, and unlike the cheap-regimen cases in this archive the harm here was to the body, not merely to the standard of evidence.

NOTES

The intervention is the family of arsenic nostrums sold for figure and complexion: complexion wafers, tonics, arsenical soaps, and the slimming “arsenic diet” tablets that Zarzo and colleagues record as advertised to speed the metabolism. The unifying promise was effortless beauty and slenderness from a small daily dose; the unifying reality was a cumulative poison taken over long periods. The category is oral, the price tier mass (these were cheap over-the-counter products), and the regulatory status banned: arsenic is not a permitted ingestible beauty aid in any modern jurisdiction. The intervention sits with the Byers radium tonic in the archive’s small set of cases where the marketed substance was not merely unproven but actively toxic.
