Eyelash extensions are semi-permanent fibers attached to your natural eyelashes to make them appear longer, fuller, and darker. They are designed to enhance the appearance of your eyes by adding volume and length to your lashes, creating a more dramatic and glamorous look. Unlike false eyelashes, which are applied as a strip and removed after each use, eyelash extensions are individually applied to each natural lash using a specialized adhesive, allowing them to last several weeks.
