The Polygel is more flexible than acrylic, stronger than hard gel, and lighter than both. This makes it a true hybrid between hard gel and acrylic nails! Used to build, bring volume and shape the base of the nail, the Polygel is an excellent base for your gel manicure. You can top with soak off gel polish or wear it just like that. Formula & Curing time: Clear Natural nail prep is the same as for gel. Requires: Base Coat & Top Coat The Polygel is not self-levelling like the builder gels but stays where you place it, which makes it easy to work with. No tacky layer after curing. Polygel nails do not experience heat spikes during curing. 2 minutes by UV Lamp, 30sec by LED Size of the tube: 30g
