What does argyria mean?
Argyria is a rare medical condition in which silver, absorbed into the body over a prolonged period, accumulates in the skin and other tissues and produces a striking, irreversible bluish-grey discoloration. The condition most often results from ingesting colloidal silver dietary supplements, taking silver-based medications, or from long-term occupational exposure among workers handling silver compounds, such as those once employed in photography and metalwork. Unlike ordinary bruising or the temporary blue tint of cyanosis, argyria does not fade: the silver particles remain embedded in the tissue indefinitely, and no established treatment reliably restores normal skin colour. The word derives from the Greek 'argyros', meaning silver, and belongs firmly to the vocabulary of medicine and toxicology rather than everyday speech. It is frequently cited in public-health warnings about unproven alternative remedies, making it a memorable example of how a supposedly harmless supplement can cause permanent cosmetic harm.
nounA rare condition caused by prolonged exposure to or ingestion of silver or silver compounds, in which silver deposits in the tissues turn the skin and mucous membranes a permanent bluish-grey colour.
- A permanent bluish-grey discoloration of the skin and mucous membranes caused by the deposition of silver or silver compounds in the body's tissues, usually following prolonged ingestion or occupational exposure to silver.
"After years of drinking colloidal silver as a supposed health tonic, he developed argyria, leaving his skin permanently slate-grey."
"The dermatologist immediately recognized argyria from the patient's uniform slate-grey complexion and his history of colloidal silver supplements."
"Workers in early photographic processing plants sometimes developed localized argyria on their hands from repeated contact with silver nitrate."
Rarely pluralized; the singular form is standard even when referring to multiple cases, which are simply described individually.
"Several cases of argyria were reported among the exposed workers."
The 'Blue Man' who turned permanently grey after self-medicating with colloidal silver wasn't wearing makeup — he had argyria, and no treatment can reverse it.

Etymology of argyria
Argyria comes ultimately from the ancient Greek 'argyros' (ἄργυρος), meaning silver, which itself may be linked to Indo-European roots also reflected in Latin 'argentum'. The term entered English through medical Latin during the nineteenth century, when physicians were systematically naming heavy-metal poisoning conditions. It shares its Greek root with words such as 'argentine' (silvery) and 'argentiferous' (bearing silver), and the element's Latin name survives in the chemical symbol Ag.
How argyria is actually used
Strictly a medical term, used almost exclusively in clinical, toxicological, and scientific contexts; it would rarely appear in casual conversation. It carries no figurative or informal usage.
Easily confused with argyria
Cyanosis is a bluish tint to the skin caused by poor oxygenation of the blood and is reversible, whereas argyria is a permanent grey-blue pigmentation caused by deposited silver.
Argyrosis is an older or more general term for silver deposition in tissue, while argyria typically refers specifically to the visible generalized skin discoloration.
