Eyeliners Natural look with the implantation of pigments in the lash line, called "lash enhancement", is preferred by many people. For those desiring a more visible or dramatic effect, the line can be placed above the lash line to the thickness desired. Permanent enhancement of the lash line is perfect for those who are allergic to conventional makeup and for those wearing contact lenses. But whether or not we have special needs, we all can appreciate seeing our eyes beautifully hightlighted without fear of smudging or running.
