- A sponge with a nap that glides across the skin. Applies and blends minerals like no other sponge and give them an extra boost of staying power as they are smoothed more deeply into the complexion for a finish that lasts all day. It's the first item professional makeup artists reach for and for good reason: there's nothing else like it. A synthetic, non-latex sponge. Use to apply and blend minerals or add more for camouflage. Spritz with any jane iredale Hydration Spray and use as a quick makeup remover. Wash sponge frequently.
