Yves Saint Laurent Make Me Blush liquid blush is a delightful liquid blush with a weightless consistency and a natural matte finish. They melt on the skin and blend very easily, creating an elusive transition like a natural blush. Due to this property and the high degree of pigmentation, any blush can be created from them, from barely noticeable refreshing to bright, for fantasy or evening looks. Blush can be applied to clean skin, as well as over a foundation, and in both cases, they blend perfectly and last up to 12 hours.
