The Build is designed to give the nail plate a desirable shape for Gel Polish. When the nail is damaged permanently without showing signs of Onychomycosis Build will give a c curve to the nail plate. Build can also be used when the nails require more strength and the free edge is thin. You can also slightly extend the free edge to protect the nails. The new colours also provide an opportunity to camouflage the nails and give a healthy natural sheer colour.
