UV nail polish is a mixture of UV gel and colored nail polish pigments. The varnish is applied normally like its normal counterpart, but is then cured under a UV lamp.
While conventional nail polish often chips after just one or two days, UV polish lasts up to four weeks. If you don't want to use UV polish, but still want long-lasting beautiful nails, you can use nail foils. These are available in two different versions: normal films and UV films. The products promise a shelf life of around two weeks.
