MAC Opal Beach Mineralize Rich Lipstick ($25.00 for 0.14 oz.) is a light, peachy gold with warm, golden pearl. It had medium coverage that didn't build beyond semi-opaque coverage. The texture was thin, balm-like, and comfortable to wear, though it emphasized every imperfection on my lips and pulled into lip lines immediately and only worsened over time. It lasted for three hours on me (not at all close to the six hours promised!).
