Gel nail polish is a popular beauty treatment, but does it contain metal? This question has been the subject of much discussion, particularly in relation to MRI scans. Some people have been instructed to remove all nail polish before an MRI scan, as pigments can contain metal which may cause thermal burns. However, others have not been asked to remove their nail polish and have experienced no issues. A study by the School of Public Health found that some nail polishes contain toxic metals such as antimony and aluminium, although these metals were not disclosed as ingredients. While gel nail polish consists mostly of methacrylate compounds, photoinitiators, and plasticizers, it is unclear whether or not it contains metal.

What You'll Learn
Gel nail polish and MRIs
It is unclear whether gel nail polish contains metal. While some sources claim that gel nail polish contains metal, others assert that it does not. It is important to note that the presence of metal in gel nail polish could pose a safety risk during an MRI scan.
Some individuals have reported being instructed to remove all nail polish, including gel polish, prior to undergoing an MRI scan. This is because certain metals, such as titanium dioxide, iron oxide, and aluminum silicate, found in some nail polishes, can react to the strong magnetic fields generated by MRI machines, potentially causing thermal burns or interference with the scan results.
However, there are conflicting reports, with some individuals stating that they have undergone MRI scans without being asked to remove their gel nail polish. It is possible that the presence of metal in gel nail polish may depend on the brand or specific product used. Additionally, the type of MRI machine and the protocols followed by the medical facility may also play a role in determining whether gel nail polish needs to be removed prior to the procedure.
To ensure safety, it is generally recommended to remove all nail polish, including gel polish, before undergoing an MRI scan. This is because even small amounts of metal in the nail polish could potentially cause issues during the scan. Furthermore, in the event of a medical emergency, the presence of nail polish can interfere with oxygen monitoring and the assessment of perfusion, or how well blood is circulating to the extremities.
While gel nail polish can be removed using polish remover, it is important to note that hospitals typically only stock regular polish remover, which may not be effective for removing gel polish. Therefore, it is advisable to remove gel nail polish prior to arriving at the hospital to avoid any potential complications or delays in receiving medical care.

Metallic pigments in nail polish
It's important to note that metallic nail polishes may contain small amounts of metal. While this is usually not an issue, it's recommended to avoid wearing metallic nail polish when undergoing an MRI scan, as even tiny bits of metal can cause thermal burns. However, opinions vary, and some people have reported wearing metallic nail polish during MRI scans without any issues.
Gel nail polishes, including metallic gel polishes, are a popular choice for those seeking long-lasting manicures. Gel nail polishes are cured under UV or LED lights, which allows them to adhere strongly to the nail and gives them their characteristic flexibility and chip resistance. When it comes to removing gel nail polish, it's important to note that regular nail polish removers may not be effective, and professional removal may be required.
If you're looking for a metallic nail polish option, there are several brands that offer a variety of colours and finishes. For example, TGB offers silver cat-eye gel and black studio gel for creating zebra-patterned nails. Cirque Colors also offers a range of metallic nail polishes, including neutrals, pastels, brights, and lights, all of which are Leaping Bunny Certified and free of animal testing.

Gel nail polish ingredients
Gel nail polish is formed of methacrylate compounds and photoinitiator compounds like benzoyl peroxide. Photoinitiators absorb ultraviolet light and split into radicals that kick-start polymerization. Two other commonly used photoinitiators are benzoyl peroxide and diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide. The monomers that the photoinitiator pushes to polymerize are a mixture of various methacrylates. Hydroxyethyl methacrylate (HEMA) is a major component of many gel polishes and can cause allergic reactions in some people. Di-HEMA trimethyl- hexyl dicarbamate, another common ingredient, has two methacrylate groups and can function as a cross-linker between polymer chains.
Plasticizers are added to gel nail polish to give it its strong but flexible nature. Methyl Acrylate is a colorless organic compound with a signature acrid odor. It’s found in most nail polishes, including gel nail polish, for its adhesive properties. It’s also found in many other things, including some paints.
Butylated Hydroxyanisole (BHA) is an antioxidant made up of two isomeric organic compounds. It’s a waxy solid used as a food additive and in cosmetics. It’s also found in some gel nail polishes and has been linked to cancer, although it is not considered dangerous when applied to nails.
Gel nail polish dries under a UV or LED light instead of in oxygen, like regular nail polish. The ingredients react with the light and grip onto the nail, making gel manicures longer-lasting than regular nail polish.
It is important to note that some people have reported allergic reactions to certain gel nail polishes, and there have been concerns about the potential health risks associated with the use of UV or LED light during the curing process.

Vegan gel nail polish
While gel nail polish is extremely popular due to its versatility and longevity, there are concerns about the presence of metal in the product. This is particularly relevant for individuals undergoing MRI scans, as even tiny bits of metal can cause thermal burns.
Gel nail polish is composed of methacrylate compounds, photoinitiator compounds like benzoyl peroxide, and plasticizers, which give it its characteristic strong yet flexible nature. The concern about the presence of metal in gel nail polish is not unfounded, as some polish additives can be metallic, and it is challenging to determine if there are any metallic components in the polish.
However, for those seeking an alternative, vegan gel nail polish is available. Brands like ORLY offer gel nail polishes that are 100% vegan and Leaping Bunny Certified. Madam Glam is another brand that offers vegan gel nail polish, and their Green Flash product is an LED gel alternative that lasts about 11 days and can be removed without acetone. Manucurist is a completely vegan nail care and colour brand.
It is worth noting that while some gel nail polishes may be vegan, they might not be certified as such. It is always a good idea to check the ingredients and do some research before purchasing to ensure that the product aligns with your values and meets your desired standards.

Toxic metals in nail polish
While gel nail polishes do not seem to contain metal, metallic nail polishes do contain toxic metals, including antimony and aluminum. These metals are not disclosed as ingredients, and while most polishes do not contain metals at dangerous levels, some nail polish finishes have been found to contain levels of antimony exceeding cosmetics guidelines.
A study by the School of Public Health, published in the International Journal of Hygiene and Environmental Health, evaluated metals in the new generation of metallic nail polish finishes, as well as on nail salon surfaces and in the bodies of nail salon workers. The study found that some nail polishes contained toxic metals, including antimony and aluminum, which were not disclosed as ingredients. While the levels of these metals were not considered toxic, they can contribute to overall exposure for both workers and consumers.
The study also found that polishes with metallic finishes had higher levels of tin than those without, and red polishes had higher levels of barium and strontium. Additionally, aluminum, barium, iron, and magnesium were found in polishes that disclosed them as ingredients. However, the polish with the highest level of aluminum was a metallic finish that listed mica as an ingredient, which is known to sometimes contain aluminum.
The presence of toxic metals in nail polish is a concern, especially for nail salon workers who may be exposed to these metals regularly. These metals can be inadvertently introduced through the use of certain minerals and colorants in new finishes, even if they are not added as intentional ingredients. It is important for consumers to be aware of the potential presence of toxic metals in nail polishes and for manufacturers to disclose all ingredients and potential contaminants.
