It’s time for makeup to do MORE. And, we’ll start with Iron Dioxide. This “IT” ingredient helps makeup maintain a realistic texture, mimicking the look and feel of skin. 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.
