This full coverage foundation works remarkably well on light, dry skin.  We initially spread the foundation directly on skin, and then worked the foundation across the skin manually to even the coverage and to avoid a caked appearance.  Note that a good-quality makeup brush would work as well.  To make the test as fair as possible, we applied on one side, and left the other side clean.  Once the foundation is worked into the skin it almost seems to disappear, but a mirror comparison showed that the difference with and without the foundation was dramatic.  Many minor blemishes were covered, and skin tone was much more uniform.  Darker blemishes showed through, but were reduced in color.
