LCN toe nails are the market leading brand for safe,non porous,long wearing gel nail extensions,they CAN NOT be removed by soaking in acetone (so must be removed by an LCN technician,if you pick or pull them you will damage your nails this can take months to regenerate) and are therefore the only nail brand you can wear polish over and change as often as you like without damaging your gel nails! giving you endless colour options from day to day,they were the first gels developed specifically for foot care.
