Eyelash extensions are semi-permanent fibers that are glued to your natural lashes to make them appear longer, thicker and darker. The goal of lash extensions is to give the eyes a made-up appearance without the use of mascara or other eye makeup. Not only do they add a natural pop to your face, they also help create a more youthful appearance overall. Your eyes will look bigger & brighter. Plus, lashes actually enhance the color of your eyes, too.
