Lead is a neurotoxin that can cause health issues, especially in children and pregnant women
Lead is a naturally occurring toxic metal found in the Earth's crust. It is a neurotoxin, and exposure to it can cause a variety of health issues, especially in children and pregnant women.
Neurotoxicity occurs when exposure to certain substances, such as lead, alters the normal activity of the central nervous system and damages nervous tissue. Lead has been shown to pass through the blood-brain barrier and cause damage to the prefrontal cerebral cortex, hippocampus, and cerebellum, leading to a range of neurological disorders, including brain damage, mental retardation, behavioural problems, nerve damage, and possibly Alzheimer's, Parkinson's, and Schizophrenia.
Children are particularly vulnerable to the toxic effects of lead and can suffer permanent adverse health impacts, especially on their developing brains and central nervous systems. Lead exposure can cause a range of issues in children, including intellectual and behavioural deficits, such as hyperactivity, fine motor function and hand-eye coordination deficits, and lowered performance on intelligence tests. It can also lead to reduced intelligence quotient (IQ), behavioural changes, including reduced attention span and increased antisocial behaviour, and reduced educational attainment.
Pregnant women should also be cautious of lead exposure, as it can cause reduced fetal growth and preterm birth. Additionally, lead exposure in adults can cause long-term harm, including an increased risk of high blood pressure, cardiovascular problems, renal disease, decreased fertility, cataracts, nerve disorders, muscle and joint pain, and memory or concentration problems.
While the specific presence of lead in gel nail polish was not found in the search results, it is known that toxic elements, such as lead, have been found in nail polish, particularly in metallic shades and finishes. These toxic elements can be inadvertently introduced through certain minerals and colorants used in the new finishes. Therefore, it is important to be aware of the potential presence of lead in nail polish and take precautions to minimize exposure, especially for children and pregnant women, who are more vulnerable to its harmful effects.

Lead and other heavy metals are found in nail polishes, but are not always disclosed as ingredients
Lead and other heavy metals have been detected in nail polishes, including those of the gel variety. A pilot study from 2017 tested 40 nail polishes, 9 technicians' urine samples, and 20 technicians' toenail clippings from 8 nail salons in the Boston area. The study found that while aluminium, barium, iron, and magnesium were disclosed as ingredients, antimony was not, despite being present in concentrations above existing cosmetics guidelines in 5 (13%) of the samples.
Other heavy metals, such as lead, cadmium, nickel, manganese, chromium, arsenic, cobalt, and mercury, have also been found in trace amounts in some nail polishes. These metals are not always disclosed as ingredients and can be harmful to human health. For example, lead is a neurotoxin that can cause a range of health problems, especially in children and pregnant women. It can result in cognitive deficits, behavioural issues, and developmental delays in children, and hypertension, kidney damage, and reproductive issues in adults.
The presence of heavy metals in nail polishes is concerning, as these products are applied directly to the nails, which can absorb chemicals. While gel polishes are cured under a lamp, potentially reducing the risk of chemical absorption, the curing process itself carries risks, as the UV light can cause cellular damage and increase the risk of skin cancer.
It is worth noting that the study's findings regarding antimony concentrations were not linked to specific colours or effects of the nail polishes. However, the highest level of aluminium was found in a polish with a metallic finish, and the highest magnesium concentration was detected in a neon polish.
To address these concerns, some nail polish brands advertise their products as "five-free," "seven-free," or "ten-free," indicating that they are free from specific harmful ingredients. For example, "five-free" polishes do not contain formaldehyde, toluene, dibutyl phthalate, formaldehyde resin, or camphor, all of which have been linked to various health issues.

The use of UV lamps to cure gel nail polish may increase the risk of skin cancer
While gel nail polishes have gained popularity for their long-lasting and chip-resistant qualities, concerns have been raised about the potential health risks associated with their application, specifically regarding the use of UV lamps for curing the polish. The question arises: Does the use of UV lamps during gel manicures increase the risk of skin cancer?
UV lamps, commonly used in nail salons, emit ultraviolet radiation, primarily in the form of UVA rays. These rays are known to cause premature skin aging and have been linked to an increased risk of skin cancer. The concern is heightened as some individuals may undergo frequent gel manicures, potentially exposing their skin to UV radiation repeatedly.
Research has indeed found a connection between UV light exposure from nail lamps and skin damage. A study published in Nature Communications exposed human and animal skin cells to UV light from nail dryers, observing significant cell death after 20 minutes, with three such sessions resulting in 60-70% cell death. This finding highlights the potential harm that UV nail lamps can inflict on the skin.
However, it is important to note that the overall risk of developing skin cancer from UV nail lights is considered low, according to current research. The probability increases with cumulative use, meaning frequent gel manicures could potentially elevate the risk. Experts recommend taking precautionary measures, such as applying a broad-spectrum (UVA/UVB) sunscreen to the hands before UV light exposure or wearing fingerless gloves during the manicure process to provide added protection.
While the link between UV nail lamps and skin cancer requires further investigation, it is advisable to limit UV light exposure and take protective measures to safeguard your skin when opting for gel manicures.

The use of toxic chemicals in nail polishes, such as formaldehyde, can cause allergic reactions and respiratory issues
While gel nail polishes are unlikely to have long-term negative effects on nail health if used sparingly, they may contain toxic chemicals such as formaldehyde, which can cause allergic reactions and respiratory issues.
Formaldehyde is a preservative that can be found in nail polish, nail hardeners, and fingernail glue. It is a potential cancer-causing substance recognised by the National Cancer Institute and is among the most common substances that trigger allergic contact dermatitis. Exposure to formaldehyde can lead to allergic reactions, skin irritation, skin depigmentation, loss of nerve sensation, coughing, asthma-like attacks, wheezing, and difficulty breathing. Formaldehyde is especially dangerous for nail salon workers and their children, putting them at risk of chronic health issues such as asthma, convulsions, nausea, and miscarriages. The substance is banned in Japan and Sweden, and its use is restricted in the European Union.
Other toxic chemicals found in nail polishes that can cause similar issues include toluene, dibutyl phthalate, formaldehyde resin, and camphor. Toluene, found in conventional nail polish removers, can cause neurological damage, decreased brain function, impaired breathing, hearing loss, nausea, reproductive impairment, immune system toxicity, and blood cancers. Dibutyl phthalate, a member of the phthalate family, is used to minimise chipping but can lead to nausea and irritation of the eyes, skin, nose, mouth, and throat. Formaldehyde resin, a by-product of formaldehyde, can be found in many nail polish formulas and has been shown to cause severe skin irritation and allergic reactions. Camphor, which gives conventional nail polishes their glossy appearance, has been linked to organ damage, including liver dysfunction.
To minimise the risk of exposure to these toxic chemicals, consumers can opt for nail polishes that are marketed as "five-free," which means they are free from formaldehyde, toluene, dibutyl phthalate, formaldehyde resin, and camphor. Additionally, it is recommended to be cautious when choosing nail polish brands to avoid exposure to dangerous toxins.

The accumulation of dried gel nail polish in salons can pose health risks to technicians and clients
The accumulation of dried gel nail polish in salons can indeed pose health risks to technicians and clients. While gel nail polish is a popular choice for its quick-drying and long-lasting qualities, there are several associated health risks that need to be addressed.
Firstly, the presence of toxic heavy metals in nail polish, including lead, nickel, manganese, and chromium, poses a potential hazard. Although these metals may be found in trace amounts, their accumulation in salons over time could result in exposure for both technicians and clients. For example, lead and nickel have been detected in nail salons, with concentrations of <0.40 μg/g for lead and <0.67 μg/g for nickel. Antimony, an element not disclosed as a nail polish ingredient, was found in concentrations above existing cosmetic guidelines in several polishes. These toxic metals can inadvertently end up in nail polishes through the use of certain minerals and colorants in metallic finishes.
Secondly, the curing process of gel nail polish under UV or LED lamps has raised concerns about potential DNA damage and increased risk of skin cancer. Studies have found that UV exposure from nail dryers can lead to cell death and may contribute to rare cancers on the nails and fingers. This is a significant concern, especially for technicians who are regularly exposed to UV light during the curing process.
Additionally, the removal process of gel nail polish can be detrimental to nail health. Soaking nails in acetone, aggressive buffing, and peeling can result in severe brittleness, dryness, and weakening of the nails. This can make the nails more susceptible to infection and other issues.
To mitigate these risks, it is essential to prioritize the safety of both salon clients and technicians. Proper ventilation and regular cleaning of salon surfaces can help reduce the accumulation of dried gel nail polish and potential exposure to toxic metals. Technicians should also be mindful of the potential hazards and take necessary precautions, such as wearing protective gear and ensuring proper waste disposal. Clients can reduce their exposure by opting for alternative manicure methods, such as regular nail polish or dip powder, and by limiting the frequency of gel manicures.
In conclusion, while gel nail polish offers convenience and durability, the accumulation of dried gel polish in salons and the associated health risks should not be overlooked. It is crucial to strike a balance between enjoying the aesthetic benefits of gel manicures and prioritizing the well-being of all involved.
