Back in Fall of 2011, OPI announced the launch of Gelcolor, a professional line of full-gel Lacquers for manicures and pedicures that can last two to three week (or longer as now we know some can keep them longer). Gelcolor applied as easily as regular nail lacquer, and cured with a LED vs UV curing saving alot of time (cured almost four times faster). It orginially started out with 28 of OPI’s most iconic colors with a base and top coat. Gelcolor is LED cured for 30 seconds per coat (including base and top!).
