M.A.C Prep Prime 24 Hour Extended Eye Base (Eye Makeup Base), 10g

Best Seller. A colorless eyeshadow base that enhances the color of the eyeshadow you apply afterwards and keeps the fresh finish for a long time. The formula is resistant to moisture and sweat, preventing eyeshadow from creasing or fading. It can be used on the end of the eyebrows, which are prone to fading, so it can also be used around the entire eye area.
