O MMA é perigoso e, por isso, não deve ser usado para fazer unhas artificiais

This is false.

The effect of exposure to humans is well understood

Metacrilato de metila monômero (MMA) is used all around the world for dental prosthetics, contact lenses, and is even implanted into the body as a bone cement, so the effect of exposure to humans is well understood. MMA is NOT considered to be a cancer causing agent nor does it damage unborn fetuses. These are myths! Even so, there are several reasons to avoid MMA monomer as a revestimento de unhas.

Traditional products reduce the need to over file

MMA nail products do not adhere well to the placa ungueal, so profissionais de unhas must shred the surface of the nail plate with an abrasivo, coarse grão arquivo, causing thinning and weakening in order to ensure the enhancements adhere to the nail plate. Traditional products are designed to adhere to the unha natural plate without the need to over file the nail plate.

MMA creates the hardest and most rigid nail enhancements

They are very difficult to break. If jammed or caught, the overly filed and thinned natural nail plate is much more likely to break than the MMA aprimoramento. This can lead to serious nail damage and possible subsequent bacterial infection.

MMA enhancements are extremely difficult to remove

This is because of the filing techniques used to make them adhere and because they don’t easily dissolve in product removers. Therefore, MMA enhancements are usually pried from the nail plate, creating still more damage to the overly thinned nail plate.

The information above applies ONLY to MMA monomer. Powders containing MMA should really be called PMMA (poly methyl methacrylate). PMMA has completely different química estrutura/properties and is considered safe for use in artificial nails. PMMA in a sheet form is called Plexiglas™ and Lucite™.
