Eyelash extensions are a cosmetic application used to enhance the length, curl, fullness, and thickness of natural eyelashes. The extensions may be made from several materials including mink, silk, synthetic, human or horsehair. The main method of applying the extensions is by using a cyanoacrylate adhesive to apply the extension(s) to the natural lash 1-2 mm from the base of the natural eyelash, never making contact with the eyelid.
