What makes The1 Builder Gel™ stand out?

Developed by Gel Co London, The1 Builder Gel™ offers nail technicians the ability to strengthen their clients’ natural nails safely and effortlessly. It allows for the construction of overlays without the need for extensions.

The1 Builder Gel™ features a self-levelling, medium viscosity, and is HEMA-free. It can be applied directly onto natural nails, serving as a primer, base, and builder in one. Use it in multiple thin layers to fortify nails or as a natural nail overlay to support the growth of weak and brittle nails. Once cured, it forms a robust soft gel that resists chips and breakages and can be infilled or removed with 100% acetone. It is designed to be worn alone — finished with the exclusive Diamond Endurance Top Coat for a natural, diamond-like glossy look — or as a foundation for creative designs using our vibrant, often one-coat, HEMA-free coloured gels or dazzling glitter gels.

Which The1 Builder Gel™ shades are suitable for building extensions?

The1 Builder Gel™ shades like The1 Sif (White) and The1 Bona Dea (Clear) are specially formulated to be used directly on nails without needing a primer or base coat.
