To get really luxurious lashes, first apply a primer before you put on mascara. One that we love is Guerlain Divinora Supercils Base Fortifying Primer. Supercils is an essential makeup base for lashes. Its innovative formula nourishes and beautifies lashes, treating each lash and preparing them for a truly magnificent, long lasting mascara application. Supercils’ nourishing formula strengthens and promotes healthy lashes that will look shiny, full, and voluptuous.
