what is the difference between powder nails and acrylic nails?
"Acrylic is liquid and powder, gel is gel. ... If they mix liquid and powder and mush it on, it's acrylics. And if they paint your nail and then sprinkle powder on, it's dip. Don't let them literally dip your nails into a jar of powder — that means they're using that same powder on multiple people, which is unsanitary.)
