The style of Permanent Eyeliner recommended is known as a Tightliner or Lash Enhancement. It enhances the eyes with a soft color effect or a dark defined line placed at the base of the lashes.  When your eyes are open your lash base appears thicker. You won’t see the Tightliner when your eyes are closed. Jill doesn’t do thick or winged permanent liner because the thicker designs don’t age well. A Tightliner is a great base to add more makeup to if desired. Lasts 2-5 years.
