It is a single-phase, self-leveling building gel with an innovative 12-free-of formula free of the strongest allergens and irritants. Inveray Builder Gel is designed for effortless sculpting different shapes of nails of any length. It is also great for hardening and strengthening the natural nail plate, which is weak and brittle, as well as for the extension of natural nails or the reconstruction of bitten/broken nails. Builder Gel is a self-leveling product and is viscous enough to prevent it from flowing onto the cuticles. Under the influence of the heat of the hand, the gel becomes even more plastic and it is easily spread with a brush, giving the nails the right shape. It hardens evenly and smoothly, without the formation of pores. The cured gel is susceptible to filing, which saves time on developing the appropriate shape of the nail, and at the same time, during filing no air pockets are formed on the prepared edges.
