Permanent eyeliner or eyelash enhancement helps women and men enhance the appearance of their eyes. It eliminates the need to outline eyelids with liquid liners or pencils and improves the appearance of missing, thin, or light colored lashes. Permanent eyeliner allows people to swim, shower, or exercise without having makeup smudges. It provides safety and convenience to people with oily skin, vision problems, or unsteady hands. Eye doctors (Ophthalmologists and Optometrists) also recommend permanent eyeliner to patients who wear contact lenses, have watery eyes, or are allergic to regular makeup.
