Guerlain’s Noir G Bee Primer lash-plumper serum combines a caring formula with the treasures of the bee for a 24 hours enhanced make-up result: lashes are visibly stronger and more beautiful day after day. Its lash care formula coats lashes one by one to prepare them for make-up and offer them triple action on volume, curl and length. Thanks to its curved brush, the lash fringe fans out to create a 360 effect. Noir G Bee Primer can be used on its own as a night mask or in combination with your mascara.
