Are gel nails applied with a powder (a "gel powder") or only liquid/gel?

I was told that gel nails still use a powder but it's a "gel powder" and then it's finished with the liquid/gel topcoat UV gel. Is this dishonest because I read that gel nails should not be using any powder - that the powder is acrylic. I heard both - please someone help me get to the bottom of this. show more I was told that gel nails still use a powder but it's a "gel powder" and then it's finished with the liquid/gel topcoat UV gel.
