The gels apply like a polish, with twist cap and applicator, but are cured in a lamp like gels. The gels come in an array of colors, and cure in a LED lamp in 30 seconds or cure in two minutes in traditional UV lamps. Gelish stays on nails for three weeks with no chipping or peeling, and soak completely off in only 15 minutes. When applied with Gelish FOUNDATION Base Gel, each Gelish Polish will do approximately 40 full sets of nails.
