Nail files

limes à ongles professionnellesYou are probably used to using cardboard files or metal ones without having paid attention to the grain on each sides. You have to be careful because some are rougher and some are softer and they do not do the same thing. In the professional nail world, you will find that most files go from 80 to 240 when it comes to the grain.

80 grain files

The smaller the number the rougher the grain. 80 is usually the rougher you can get in a file. It is mostly used for false nails, acrylic or nail with a thick layer of polish or gel on them. It can also be used on the feet. It is not recommended to use that grain on natural nails because it is too rough and it can hurt you and damage the nail .

100 grain files

The 100 grain is also one of the roughest, but less than the 80. It is also used on acrylic and false nails. This grain is still too rough to use on natural nails.

180 grain files

This type of grain is the middle ground. Not too rough but not too soft. It might be too soft for false nails and acrylic but perfect for gel, UV polish, regular polish and natural nails.

240 grain files

The 240 grain is the softest and the best for natural nails. You can use it to remove regular polish or to shape the natural nail and smooth the surface. It is too soft to work with other types of nail enhancements.
