There are many AirBrush makeup products out there, some better than others. What is your favorite? I have tried many, Mac, Luminaire, and now Graftobian.
Make sure your skin is not too oily before applying your AirBrush foundation, use a little moisturizer that is not too greasy. AirBrush doesn’t mix well with oils. Before applying any powders, blush etc. let the foundation set for a moment.
