ok, im not necessarily a newbie to gelish. However, ibd kinda has me stumped.. i tried using the pink builder gel and cure it under gelish led lamp and it seemed not to cure..here is what i did.. I used the foundation to gelish and used the ibd builder gel and cured for like 45 seconds and it seemed to want to rub off. My question is: was it the foundation and or the light or both?
