It’s time for makeup to do MORE. And, we’ll start with iron oxide. When iron oxide is in makeup, it mimics the look and feel of skin, which helps your face maintain a realistic texture. And, isn’t that the entire purpose of wearing makeup to begin with? Iron oxide delivers all-day, stay-put power to your airbrush makeup masterpiece, making sure your look doesn’t budge or smudge.
