This is one of those highlighters that just delivers consistently. It's a beautiful and incredibly pigmented champagne colour that highlights your cheeks to the gods! The formula is buttery and the application is smooth as silk. If you're fair skinned then this is perfect for you (I rank it better than Mac Lightscapade on fair skin). I have a medium to medium deep skintone. In winter it works really well for me. In summer its a little light, but I can still use it, using a light hand. It mixes well with other highlighters, especially TheBalm Betty Lou-manizer which is marketed as a bronzer (it's really a deep highlight colour). Mixed together they make a beautiful colour. Now TheBalm have just released Bonnie-Lou Manizer which looks to be the perfect colour between Mary-Lou and Betty-Lou.
