CONCEALER are not only for concealing, they are also for highlighting. Just load up the tip of your brush and dab on the blemishes and brown spots carefully avoiding the area around them. To camouflage red areas, use a concealer that is more or less the same shade as your foundation. This will minimized the area. And you can even use a concealer to highlight the areas you want to emphasize (ok they do more than concealing) the chin, the center of the forehead, the area just below the outer edge of the brow, below the lower lip just to name a few.
