my thoughts on the formula: The color applies opaque in a single pass with a smooth, even finish. Extra Rich Lipsticks are absolutely a luxury item; they are pure decadence. The texture is incredibly smooth and creamy without being slippery or heavy. It imparts a nice level of moisture on lips and never feels drying. The formula also de-emphasizes lip lines after about fifteen minutes of wear. I get between four and six hours of wear.
