Nails Of The Day "Builder Gel 90" is an advanced professional modeling gel that brings true luxury to salon work thanks to its unique texture infused with a sophisticated pearl shimmer (mother-of-pearl effect). Formulated with a state-of-the-art low-temperature composition, it dramatically minimizes the chemical exothermic reaction (heat spike) inside the lamp, ensuring an exceptionally comfortable and pain-free curing process even for clients with very thin, damaged, or highly sensitive nail plates. Its medium-viscosity consistency possesses outstanding self-leveling properties – the material flows smoothly under the brush and creates a perfectly flat surface within seconds, allowing nail technicians to quickly build correct architecture (apex) and elegant salon lengths on forms. It provides robust structural rigidity, high wear resistance, and C-curve stability for up to 4 weeks, while its elegant pearl finish beautifully masks imperfections, creating a finished, magical look that eliminates the need for additional color application.
