The market provides such an overwhelming variety in nail polish that one is bound to consider changing the shade on one's nails every few days. After all, trends in fashion change like the wind. Sometimes, the brand of nail polish is not very suitable to the nails, or there can be a lot of reasons for desiring a change. This is where nail polish removers enter the picture.
There is always the option between those containing acetone and those that don't contain acetone. Those without acetones certainly are a lot mild in their action, and can never harm the nails. But those containing acetone work quite quickly and remove the nail polish in a jiffy.
Acetone is a solvent with the property of being able to dissolve even plastic. It dissolves the nail polish and leaves you with a clean nail. Nail polish is actually made up of polymers that have hardened up. The solvent in nail polish removers finds its way through the molecules of the polymer in the nail polish remover, and lo and presto, the nail polish is gone.
Nail extensions, often used by stage artists, are amenable to be dissolved by virtue of the acetone content of acetone-based nail polish removers. If an acetone-based nail polish remover is used in this case, the result may be that the artist may totally lose the artificial nail. This was why non-acetone based nail polish removers were devised. Nail polish removers that don't contain toxic materials should be used if health concerns regarding using acetone or non-acetone based nail polish removers concerns you.
