Methyl methacrylate, or MMA, is a chemical compound that has been used in the nail industry since the 1970s. It is a monomer liquid that, when mixed with pre-polymerized MMA powder (PMMA), creates a strong bond. While MMA is commonly used in the dental industry, it has been banned by the FDA for use in nail liquids due to its damaging effects on nails and health risks, including permanent nail loss and respiratory issues. Despite the ban, some nail salons still use MMA due to its low cost and the misconception that it is safe for natural nails in solid/polymer form. However, it is essential to be cautious and informed about the potential dangers of MMA when choosing a nail salon.

Methyl Methacrylate (MMA) is a common ingredient in professional nail products
Methyl Methacrylate (MMA) is a chemical compound that was widely used in the early days of the nail industry. It is a monomer liquid used by nail technicians to create nail enhancements. However, due to its damaging properties, the FDA banned its use in the mid-1970s. The ban was a result of numerous complaints about personal injuries associated with MMA, including serious nail damage or loss, contact dermatitis, soreness, and infections due to breaks.
Despite the ban, it is still possible to find nail products containing MMA, especially in salons offering discounted prices. It is important to be cautious when choosing nail products and treatments, as the use of MMA can lead to several adverse effects. One of the main concerns is the potential for permanent nail damage. MMA hardens the nail to such an extent that it becomes challenging to separate it from the natural nail plate, often requiring forceful removal that can injure the nail bed and surrounding skin.
Additionally, MMA has been linked to respiratory issues and eye, nose, and throat irritations due to its vapors. It can also cause severe allergic reactions, with symptoms such as redness, swelling, numbness, and itching, which may progress to blisters or open sores. These reactions can result in a long-lasting sensitivity to nail enhancements. Moreover, the rigid nature of MMA enhancements limits the flexibility of the natural nail, making it susceptible to abrupt breakage and subsequent rapid infections.
While MMA has been prohibited in nail liquids, it is important to note that it is not banned for use in nail powders or polymers. When mixed and heated with other ingredients, MMA becomes inactive and forms a new substance called PMMA (poly methyl methacrylate), which is considered safe for use on natural nails. However, it is essential to use products with proper ventilation to control dust and vapors.

MMA is prohibited for use in nail liquids, but not in nail powders
Methyl Methacrylate, commonly known as MMA, is a monomer liquid used by nail technicians to create nail enhancements. It was introduced to the nail industry in the 1970s as a cheap alternative to other compounds. However, by the end of the decade, the FDA banned its use in nail liquids due to its damaging properties.
When applied, MMA hardens to such an extent that it becomes challenging to separate from the nail plate. This hardness can lead to the permanent loss of the nail plate if the enhancement gets caught and pulled off. Additionally, the difficulty of removing MMA means that technicians often have to pry it from the nail plate, which can damage the nail bed and injure the surrounding skin.
MMA is also associated with allergic reactions and, in some cases, permanent loss of sensation in the fingertips. It can cause skin sensitization, leading to redness, itchiness, rashes, or swelling.
Despite the prohibition of MMA in nail liquids, it is still permitted for use in nail powders. In its powder form, MMA is considered safe for use on natural nails. Once the MMA powder is mixed with other ingredients and heated, it becomes solid, and the MMA is no longer active. This new solid compound is called PMMA (poly methyl methacrylate) and is commonly found in nail powders.
Therefore, while the use of MMA in nail liquids is prohibited due to health and safety concerns, it is allowed in nail powders as long as it undergoes the proper manufacturing process to become PMMA.

MMA is not toxic, but unsuitable for nail enhancements
Methyl Methacrylate, or MMA, is a chemical compound that was banned by the FDA in the 1970s for use in nail enhancements. Despite this, it is still used in some salons. This is likely because it is a cheaper alternative to recommended products.
MMA is not toxic, but it is unsuitable for nail enhancements. When applied, MMA does not stick easily to the nail plate. As a result, the nail technician has to over-file or shred the nail surface, making the nail structure weak and susceptible to injuries. Once applied, MMA hardens to such an extent that it becomes very difficult to separate it from the nail plate. As a result, the product has to be pried from the nail plate, which can easily damage the nail bed and injure the surrounding skin.
MMA is unbreakable once fixed and, if it gets caught on something, the entire nail plate can come off as it has already been thinned and filed to fix the MMA enhancement. The FDA ruled that MMA caused serious fingernail damage, contact dermatitis (allergic reactions), and deformity.
There are many health risks associated with exposure to MMA. If you begin to feel drowsy, light-headed, dizzy, or if your hands become shaky, there is a chance that MMA is being used. MMA can also cause skin sensitization or dermatitis, resulting in skin redness, itchiness, rashes, or swelling.
EMA (Ethyl Methacrylate) is recommended as an alternative to MMA. It has a slightly different molecular structure and does not damage the nails. It is ideal for use in salons as it does not easily penetrate the nail and damage the skin and tissues.

The use of MMA can cause permanent loss and damage to the natural nail
The use of Methyl Methacrylate (MMA) for gel nails is a controversial topic. MMA is a monomer liquid used by nail technicians to create nail enhancements. While it is commonly used in dental prosthetics and contact lenses, its use in the nail industry, specifically in nail liquids, has been prohibited since the 1970s due to its damaging properties.
MMA, when applied to the natural nail, does not adhere well to the nail plate. As a result, nail technicians have to over-file or shred the nail surface to create a better bond, causing thinning and weakening of the nail structure. This makes the nails more susceptible to injuries and can lead to permanent nail damage, including nail loss.
The strong bond formed by MMA also means that it is extremely difficult to remove. Traditional removers do not work, and the product has to be pried or filed off forcefully, which can further damage the nail bed and injure the surrounding skin. This forceful removal can also cause painful breaks and tears to the natural nail, as the rigid MMA enhancement does not snap off harmlessly when caught or jammed.
Additionally, MMA has been known to cause serious skin reactions, including allergic reactions and contact dermatitis. Long-term exposure to MMA can also have adverse effects on the respiratory system and the liver.
Due to these risks, the FDA banned the use of MMA in nail liquids in the 1970s. However, it is important to note that MMA is not prohibited for use in nail powders, and once it has been mixed, heated, and solidified, it is considered safe for use on natural nails.
Despite this, the potential for permanent nail damage and other health risks associated with the use of MMA in gel nails has sparked concerns and campaigns for further bans and regulations.

MMA vapors may cause respiratory problems without proper ventilation
Methyl Methacrylate, or MMA, is a monomer liquid used by nail technicians to create nail enhancements. While it is not toxic, it was banned by the FDA in the 1970s due to its damaging properties. When applied, MMA hardens and becomes difficult to remove from the nail plate, often requiring force that damages the nail bed and injures the surrounding skin.
MMA is not used in gel nails, but it is used in nail powders and polymers. When mixed and heated with other ingredients, the monomers become solid, and the MMA is no longer active, becoming PMMA (poly methyl methacrylate), which is considered safe to use on natural nails.
The vapors produced by vaping are inhaled and can contain harmful substances. While the long-term health effects of vaping are uncertain, there is evidence that it can cause respiratory problems. For example, "popcorn lung," or bronchiolitis obliterans, is a type of lung inflammation that causes wheezing, coughing, and shortness of breath, and can lead to lung scarring and airway narrowing. This condition can be caused by diacetyl, a food additive used to enhance the taste of flavored e-liquids.
Another risk factor for respiratory issues is vitamin E acetate, a synthetic form of vitamin E found in some THC-containing vaping products. It is considered the main cause of EVALI (e-cigarette or vaping product use-associated lung injury), which has resulted in thousands of hospitalizations and dozens of deaths. Symptoms of EVALI include respiratory issues such as shortness of breath, coughing, and chest pain.
Therefore, while MMA in nail products may not directly cause respiratory issues, the use of MMA vapors without proper ventilation could potentially cause similar issues to those associated with vaping, due to the inhalation of harmful substances.
