Has copper always been used for skin healing?
The historical record says yes, supported by a number of documented incidents and examinations. The earliest written reference to copper in wound care dates to approximately 2400 BC. The mechanism behind why it worked was not understood until the twentieth century. But the empirical observation that wounds treated with copper compounds healed better and became infected less often was recorded independently across Egyptian, Greek, Roman, Aztec, and Persian medicine over a period of more than three thousand years (1).
This article traces that history from its earliest documented sources and explains what modern biochemistry has since confirmed about the mechanisms these ancient practitioners were observing without understanding.
Copper in Ancient Medicine: What the Archaeological Record Shows
The Smith Papyrus: the oldest surgical record in history
The earliest documented use of copper for medical treatment appears in the Smith Papyrus, an ancient Egyptian medical text dated to approximately 2400 BC and now held at the New York Academy of Medicine. Considered the oldest known surgical treatise in human history, the Smith Papyrus records copper's use as a sterilizing agent for drinking water and for the treatment of wounds (1). The document proceeds through empirical clinical reasoning, describing wounds, fractures, and infections with a systematic observational approach that predates the Hippocratic writings of Greece by roughly a thousand years.
The Ebers Papyrus: copper for skin conditions
A second foundational Egyptian medical text, the Ebers Papyrus (c. 1550 BC), records copper compounds being used specifically for skin conditions, including burn wounds, itching, and skin infections (1). Copper splinters, shavings, and various copper salts and oxides are described. This is the first documented record of copper being applied specifically to skin pathologies rather than open wounds.
Greek medicine: the Hippocratic Collection
By the fifth century BC, copper had become a standard treatment in Greek medicine. The Hippocratic Collection - the body of medical texts associated with Hippocrates of Kos (c. 460–370 BC) - recommends copper salts for the treatment of leg ulcers associated with varicose veins. This marked the first documented use of copper for a specifically named dermatological condition (beyond general wounds or burns) in the Western medical tradition, and evidence that copper's application to skin had by this point moved from wound sterilization to targeted therapeutic use (1).
Greek physicians also used copper preventively: to prevent infection of fresh wounds, they applied a dry powder of copper oxide and copper sulfate, and treated wounds with a boiled mixture of honey and red copper oxide (1). The Greeks had ready access to copper from the island of Cyprus, from which the Latin word cuprum and the modern symbol Cu are both derived.
Roman medicine: De Medicina and Pliny the Elder
By the time of the Roman Empire, copper compounds had become firmly established in the medical pharmacopoeia. The Roman physician Aulus Cornelius Celsus (c. 25 BC–50 AD) documented copper's use across multiple wound and skin applications in his comprehensive medical treatise De Medicina (2). Pliny the Elder (23–79 AD) described numerous copper-based remedies in his Naturalis Historia, one of the most extensive records of first-century Roman medical practice that survives (2).
Beyond Egypt, Greece, and Rome
The use of copper in medicine was not limited to the Mediterranean world. Dollwet and Sorenson's foundational 1985 review, published in Trace Elements in Medicine and drawing on ancient Egyptian papyri, Greek, Roman, Aztec, Hindu, and Persian medical writings, as well as medieval European medical literature, documented consistent and independent uses of copper as an antibacterial, anti-inflammatory, antiarthritic, and wound-healing agent across cultures that had no direct contact with each other (1). This cross-cultural convergence on the same material for the same purposes is itself a form of empirical evidence: the accumulated observation of many independent practitioners across many centuries.
In ancient Persia, the tenth-century pharmacological text Liber Fundamentorum Pharmacologiae describes powdered malachite (a copper compound) applied to boils, and copper compounds used for eye conditions (2). The Aztecs used copper oxide and malachite to treat skin conditions (2).
The nineteenth century: cholera and the copper workers of Paris
One of the most striking historical observations about copper's protective properties comes from the nineteenth century. French physician Victor Burq observed that copper workers in Paris appeared largely immune to recurring cholera epidemics that devastated the surrounding population. He documented this in 1867, noting that the pottery-making town of Aubagne, protected by copper-rich clay dust, was similarly spared (1). This observation was made decades before germ theory was fully established and long before the mechanism of copper's contact-kill antimicrobial action was understood.
Why It Worked: The Mechanism Ancient Practitioners Didn't Know
For most of human history, the practitioners described above used copper because it worked, not because they understood why. The mechanism behind copper's wound-healing and antimicrobial properties was not established until the twentieth century. Here is what we now know.
Copper and collagen: the lysyl oxidase connection
Collagen is the structural protein that keeps skin firm, elastic, and resistant to mechanical stress. Its production declines with age, contributing to wrinkles and sagging. Copper is a required cofactor for lysyl oxidase, the enzyme that cross-links collagen and elastin fibers, locking them into their structurally stable form. Without adequate copper, lysyl oxidase cannot function correctly, and the collagen framework weakens (3).
A review of multiple clinical studies published in Current Chemical Biology found that sleeping on copper-ionized pillowcases produced statistically significant improvements in skin appearance in double-blind, placebo-controlled trials (4). The mechanism is consistent with what the historical record observed empirically: copper in sustained contact with skin supports the biological processes that maintain skin structure
Copper and wound healing: reducing inflammation and supporting repair
Copper's anti-inflammatory properties are another reason it is effective in skin healing. When skin is injured or inflamed, the body triggers an immune response. Excessive or prolonged inflammation can hinder wound healing and contribute to more severe downstream effects. Copper modulates the immune response by reducing pro-inflammatory cytokines.
Research published in PLoS One found that copper not only helps prevent inflammation but plays a direct role in wound healing by moderating inflammatory gene expression, with effects measurable even after inflammation had already occurred (5).
Copper's antimicrobial mechanism: what ancient practitioners observed
The ancient practitioners who applied copper powder to open wounds were observing, without understanding, what modern microbiology has since confirmed: copper ions disrupt bacterial cell membranes on contact, killing a broad spectrum of pathogens. Research published in Applied and Environmental Microbiology demonstrated that copper surfaces reduce bacteria including E. coli and Staphylococcus aureus by over 99% within an hour of contact (3). This contact-kill mechanism is why copper became, independently across dozens of cultures, the default treatment for infected wounds long before germ theory was established.
Copper in Modern Medicine and Skin Care: Confirming the Ancient Record
The ancient practitioners documented in the first section of this article could not have known that their copper ointments were activating lysyl oxidase, disrupting bacterial cell membranes, or reducing pro-inflammatory cytokines. Modern clinical research has now confirmed the mechanisms behind what they observed. Here is where the evidence stands today.
Copper Infused Wound Dressings: from ancient bandages to regulatory approval
A 2010 study confirmed that copper oxide-impregnated dressings reduced microbial load in wounds by 99.9% without provoking irritation or sensitivity in any participant (6).
A 2024 prospective clinical study published in Health Science Reports found that copper oxide wound dressings produced a mean wound area reduction of 87%, more than twice the reduction achieved by silver dressings in the same patients, whose wounds had previously failed to respond to silver treatment (7).
Following these insights, copper-impregnated wound dressings are now approved medical devices in the United States, Europe, and Israel (7).
Copper in Skincare
Copper peptides are now a popular ingredient in many high-end skincare products due to their ability to promote collagen production and improve skin elasticity. Copper is often included in serums, creams, and masks that claim to reduce wrinkles, promote firmness, and encourage skin regeneration. Research published in The International Journal of Molecular Sciences supports the use of copper peptides in skincare, demonstrating their ability to improve skin tone and texture by stimulating collagen production and promoting wound healing at a cellular level (8).
Copper-infused fabrics: from clinical textiles to consumer applications
The application of copper to textile fibers for wound dressings, garments, and bedding is the modern extension of what ancient practitioners achieved by applying copper compounds directly to skin. A 2014 review published in Current Chemical Biology details multiple studies confirming that copper-infused socks reduce bacterial colonization and improve symptoms of athlete's foot in study participants (4).
The same research framework - copper ions in sustained contact with skin - underlies the growing category of copper-infused consumer textiles, from socks to pillowcases. The evidence base for each application varies; the foundational mechanism is consistent with four thousand years of empirical observation and modern biochemistry.
From Ancient Papyrus to Peer-Reviewed Journal: What Four Millennia of Evidence Suggests
The through-line of copper's medical history is unusually consistent. The Smith Papyrus described copper as a wound sterilizer in 2400 BC. The Hippocratic Collection prescribed it for skin ulcers in 400 BC. Celsus documented it across multiple skin and wound applications in the first century AD. And modern peer-reviewed clinical trials - published in journals including PLoS One, Applied and Environmental Microbiology, and Health Science Reports - have confirmed the mechanisms behind every one of those applications.
This is not a story of ancient wisdom being validated by modern science so much as it is a story of empirical observation being explained by modern science. The ancient practitioners who reached for copper were doing what all good practitioners do: using what worked, based on what they could observe. What they could not observe - lysyl oxidase activation, contact-kill bacterial disruption, cytokine modulation - we can measure now. The observation was always correct. The explanation just took a few thousand years.

Frequently Asked Questions
When did humans first use copper for healing?
The earliest documented use dates to approximately 2400 BC in the Smith Papyrus, the oldest surviving surgical treatise in history, now held at the New York Academy of Medicine. The text records copper's use as a sterilizing agent for drinking water and for wound treatment. A second Egyptian medical text, the Ebers Papyrus (c. 1550 BC), records copper compounds specifically for skin conditions including burns and infections (1).
Did ancient Egyptians really use copper for skin health?
Yes, with specific documentation. The Smith Papyrus (c. 2400 BC) records copper as a wound sterilizer, and the Ebers Papyrus (c. 1550 BC) documents copper compounds applied to burns, itching, and skin infections (1). A 2011 study published in the General Union of Arab Archaeologists' Annual Review provides archaeological corroboration of copper's role in ancient Egyptian medicine (9).
Did Hippocrates use copper as medicine?
Yes. The Hippocratic Collection (c. 400 BC) recommends copper salts for the treatment of leg ulcers associated with varicose veins, one of the earliest documented uses of copper for a specific dermatological condition. Greek physicians also applied copper oxide and copper sulfate powder to fresh wounds to prevent infection (1). Hippocrates is considered the father of Western medicine, and his use of copper reflects how central the material was to Greek medical practice.
Why did ancient civilizations use copper for wounds?
They used copper because it worked, though they did not know why. Modern microbiology has since established the mechanism: copper ions disrupt bacterial cell membranes on contact, killing a broad spectrum of pathogens (3). What ancient Egyptian, Greek, Roman, Aztec, and Persian practitioners were observing empirically was copper's contact-kill antimicrobial action, centuries before germ theory was established. Dollwet and Sorenson's 1985 review in Trace Elements in Medicine documented this consistent, independent use of copper across cultures with no direct medical contact with each other (1).
Is there scientific proof that copper heals skin?
Modern peer-reviewed research has confirmed several specific mechanisms. Copper is a required cofactor for lysyl oxidase, the enzyme that cross-links and stabilizes collagen fibers (3). Copper disrupts bacterial cell membranes on contact (3). Clinical trials of copper-infused pillowcases produced statistically significant improvements in skin appearance (4). Copper oxide wound dressings have achieved regulatory approval in the US, Europe, and Israel and demonstrated significantly greater wound area reduction than silver dressings in a 2024 clinical study (7). The evidence is specific, peer-reviewed, and documented across multiple independent research groups.
What did ancient Romans use copper for medically?
Roman physician Aulus Cornelius Celsus (c. 25 BC–50 AD) documented copper in his medical treatise De Medicina for wound and skin applications. Pliny the Elder (23–79 AD) described copper-based remedies in his Naturalis Historia. By the Roman period, copper and its compounds had been established as a standard part of the medical pharmacopoeia, carrying forward the Greek tradition, which had itself built on Egyptian practice (1).
What is the copper connection to Cyprus?
The Latin word for copper, cuprum, and the chemical symbol Cu, are both derived from Kypros, the ancient Greek name for the island of Cyprus. Greece had ready access to copper from Cyprus, which is also why copper was central to Greek medical practice: availability and familiarity reinforced the empirical observation that it worked for wounds and infections (1).
