The PRIMA Extension Builder has been developed to allow you to create nail extensions up to 1 cm in length. It can also be used for nail strengthening. This is a low viscosity clear builder gel that can be removed by soaking-off or filing. It is also possible to infill. For most salon clients, you can expect +4 weeks wear time. 

The IKON.iQ PRIMA gel polishes are a new technological innovation developed by our laboratories. Using a totally new pigmentation chemistry developed by our chemist, the PRIMA gel polishes only require one colour layer and yet have a natural thin look without distorting the nail shape.

PRIMA is a 3-step system consisting of a Base, colour and Top gel polish. This produces thin-looking nails that are chip-free for 4 weeks and that have an incredible shine. 


PRIMA are hypoallergenic and do not contain HEMA Hydroxyethyl Methacrylate, (HPMA (Hydroxypropl Methacrylate) or other higher risk ingredients. This means that PRIMA is a good solution to avoid allergies, but is also happily used by many Nail Technicians who developed allergies from other brands products.
