What builder gel is
Builder gel is a thicker gel you brush on to give natural nails strength and structure. It can also build short extensions.
It needs a lamp
Like gel polish, builder gel hardens under a UV/LED lamp. If you don't have one yet, see our lamp guide. Removal works like gel — see how to remove gel at home.
