The obsession with beauty is as old as time, but many ancient beauty rituals that promised radiance delivered something else: death
Long before clean beauty labels and FDA approvals, beauty was an extreme sport, with the promise of glow, pallor or seduction routinely flirting with poisoning, paralysis and death. Across centuries and cultures, cosmetics doubled as chemistry experiments, driven by rigid beauty ideals and limited medical knowledge. Beauty was, inadvertently, pain. Seen through a modern beauty lens, these beauty rituals reveal how aesthetics, power and danger often shared the same vanity mirror.
Below, the most dangerous beauty trends ever to grace a vanity table—and what they tell us about power, class and the lengths we’ve always gone to look divine.

1. Scheele’s Green

In 19th-century Europe, emerald green became the most coveted colour in fashion, made possible by Scheele’s Green, a pigment created from copper arsenite. Women wore it as gowns, gloves, artificial flowers and even hair accessories, particularly in tightly enclosed ballrooms where heat and sweat activated the toxin. As fabric rubbed against skin, arsenic was absorbed or inhaled as dust, causing sores, respiratory illness and slow organ failure—dubbed “the green death”. The danger extended beyond the wearer: seamstresses, maids and dance partners were equally exposed.
Fortunately, non-toxic synthetic dyes now recreate the same jewel tones without lethal consequences.
2. Venetian Ceruse

From Renaissance Italy to Elizabethan England, deathly pale skin signalled wealth and moral purity, achieved through Venetian Ceruse—a paste of white lead and vinegar. Applied thickly to face and neck, this lead face mask concealed scars and blemishes but quietly poisoned its users. Chronic lead exposure caused hair loss, blackened teeth, skin deterioration and neurological damage; many women layered ceruse thicker as their skin worsened, accelerating the cycle. Queen Elizabeth I, a known adherent of beauty rituals, was reportedly a heavy user.
Today, zinc oxide–based foundations and tone-up creams deliver brightness without toxicity.
3. Belladonna

In Renaissance Italy, dilated pupils were considered irresistibly sensual, prompting women to drip extracts of Atropa belladonna—deadly nightshade—directly into their eyes. The toxin temporarily enlarged pupils, creating a dreamy, aroused look immortalised in portraiture. But repeated use of the strange beauty ritual led to blurred vision, permanent blindness, heart palpitations and, sometimes, death. Beauty here was literally blinding.
Nowadays, cosmetic contact lenses and safe ophthalmic products mimic the effect without risking eyesight.
4. Radium

After radium’s discovery in the early 20th century, it was hailed as a miracle element, swiftly absorbed into luxury skincare and cosmetics like Tho-Radia creams and powders. Advertisements promised “cellular vitality” and youthful radiance through daily radioactive exposure. Instead, users suffered bone decay, anaemia and aggressive cancers, including the infamous “radium jaw”. The scandal reshaped product regulation worldwide.
Skip the radium and go for vitamin C, niacinamide and light-reflecting pigments, which deliver glow minus radiation.

5. Cinnabar

Across ancient China, Rome and the Islamic world, vivid red lips and cheeks were achieved with cinnabar, a mercury sulfide mineral prized for its rich colour. Ground into powders for rouges and lip stains, it symbolised vitality and status. Mercury, however, is a potent neurotoxin; prolonged use caused tremors, memory loss, mood disturbances and cognitive decline—the origin of “Mad Hatter” syndrome.
Thankfully, modern iron oxide pigments provide the same crimson payoff safely.
6. Bread and bird droppings

Medieval skincare and beauty rituals leaned heavily on folk remedies, especially for acne. Treatments included bread poultices mixed with bird droppings, bull’s bile or animal fats, applied directly to inflamed skin. While not chemically toxic, these mixtures were biologically dangerous, often introducing severe infections to open sores. In an era without antibiotics, this could escalate to sepsis and death.
Now, safe remedies include salicylic acid, benzoyl peroxide and hygienic dermatological care.
7. Tapeworm diet pills

Obsessed with frailty and wasp waists, late-Victorian society embraced one of history’s most horrifying weight-loss hacks: ingesting tapeworm eggs in pill form. The parasite would grow inside the host, consuming nutrients and causing rapid weight loss, but also anaemia, vitamin deficiencies and organ damage. In severe cases, migrating larvae caused fatal cysts in the brain. The concept later inspired a chilling episode of American Horror Stories.
8. Aqua Tofana

In 17th-century Italy, Aqua Tofana was sold as a harmless cosmetic tonic—clear, odourless and discreetly packaged among beauty bottles. In reality, it was a lethal cocktail of arsenic, lead and belladonna. While small topical use was possible, its darker reputation came from being slipped into food to poison abusive husbands, mimicking natural illness. Beauty, autonomy and survival intersected in a bottle.
9. Coal tar lash stains

In the 1930s, Lash Lure promised permanent dark lashes using an aniline dye derived from coal tar. Women flocked to salons for the treatment—until reports surfaced of extreme allergic reactions, ulcerated eyes and infections. One widely reported case ended in blindness and death, prompting public outrage. The scandal directly influenced stricter cosmetic safety laws in the US.
Fortunately, current mascaras and lash tints are rigorously tested under modern regulations.
10. Lead combs

Greying hair in the 18th and 19th centuries was “treated” with lead-based dyes, silver nitrate solutions or daily brushing with lead combs that darkened hair through chemical reaction. Over time, lead seeped through the scalp, causing nerve damage, headaches and the telltale wrist paralysis known as drop-hand. Many mistook the symptoms for ageing itself.
11. Foot binding

For nearly a millennium in imperial China, bound feet—ideally no longer than three inches—were the ultimate symbol of femininity and status. Girls’ feet were broken, folded and tightly wrapped to prevent growth, causing chronic pain, infections and lifelong disability. While not cosmetic in the modern sense, it was a beauty ritual enforced by social power structures. Sadly, it lasted all the way to the 20th century.
