Most drugstore lashes? They’re synthetic. Usually made from a plastic called polyester or acrylic. Think of it as a very fine, very stylish plastic broom.
Why do brands love this stuff? It’s cheap. It’s consistent. And it holds a curl like a champion. You can sleep in them (please don’t), and they’ll still look like they just came from a salon.
But—there’s always a but—they can look a little shiny. A little fake. That’s why you might see “matted” or “matte” synthetic lashes. They’re roughed up a bit to look more natural. Clever, right?
