The nail plate is composed of three layers. It is naturally the visible, outer layer that is particularly sensitive to outside elements and can very easily be damaged by too much sun, cold weather, detergents,…. Its specific formula has been developed to give nails resistance. NAIL SHIELD forms a strong physical protection to protect nails from daily tasks and other damaging elements. Then, being protected from breaking, flaking and impacts and with a combined treatment (such as MAVALA SCIENTIFIQUE and/or NAILACTAN), the nail can then correctly regenerate and strengthen itself.
