Great question and a common problem. To keep the complexion smooth, I would recommend starting with a primer to color correct, smooth the skin and extend makeup longevity. I love the Physicians Formula Mineral Wear Talc-Free Mineral Correcting primer as it not only color corrects and preps skin, but it also fills in fine lines for a more youthful appearance. I'd also suggest using a mineral powder to set your foundation and apply, if possible, with a kabuki brush for a perfectly airbrushed looking complexion.
