Builder Gel is akin to a thick, adhesive gel, distinguished by its sturdy composition, tailored for mid-length to long nails. Unlike its flexible counterpart, it maintains a rigid structure, effectively safeguarding natural nails against bending. Ideal for reinforcing and fortifying natural nails, Builder Gel offers extended durability compared to Base Gel. Moreover, it serves as a versatile option for nail extension purposes. Prior application of a base gel layer is essential, as Builder Gel lacks inherent adhesion to natural nails.
