The Primer Mascara by Rabanne is a translucent serum base that serves as a preparation step for your lashes. It not only prepares your lashes for mascara application but also provides care and nourishment. When used in conjunction with the Famous Mascara, it enhances the performance and duration of your mascara makeup result. The lashes appear significantly longer, denser, and highly curved and lifted, giving you a more dramatic and intensified lash look. This primer mascara helps you achieve a more defined and bold lash appearance while providing nourishing benefits for your lashes.
