How do I remove launchpad icon from the launchpad itself?

So after using Clean My Mac 2 for the first time I deleted 3.25GB of space from my macbook air. What was also deleted were the iconds in the launchpad, by icons I mean that when I openes launchpad you could see a space and the name of the app but you couldn't see the icon. The way to fix that was to drag all the apps from the application folder in the finder to the launchpad icon in the dock. Now all of my apps are back and launchpad is also in the launchpad now and I want to get rid of it because it is useless there. Is launchpad supposed to be inside the launchpad anyway or did it appear there because I dragged all the apps from the applications folder to the launchpad icon? Any help will be accepted. Thank You.
