Everyday use of mascara can often leave lashes in less than peak condition. A little dry and brittle today can often lead to lash fallout and mascara mayhem tomorrow. Rather than simply masking the problem with another coat, try a little injury prevention instead. Lash Building Primer is a multi-benefit mascara primer designed to help lackluster lashes reach and maintain tip-top shape. Lash Building Primer provides lashes with nourishment, optimum conditioning benefits, and protection from injury.
