Methyl Methacrylate Monomer (MMA) is banned in the U.S. because it poses significant risks of injury to the nails and surrounding skin. MMA is known to cause serious allergic reactions, skin irritations, and other health issues, which can include respiratory problems when inhaled. Additionally, products containing MMA tend to harden too excessively, leading to brittleness and potential nail damage. Unlike typical nail substances, MMA is difficult to remove from the nails, requiring more aggressive methods that can further harm the nail bed and surrounding tissue.

The characteristics of MMA and its associated risks are why authorities have chosen to restrict its use in the nail care industry, emphasizing the importance of client safety and health within the practice.
