Abstract

The method for manufacturing artificial eyelashes of the present invention includes the steps of: forming cutting lines corresponding to the artificial eyelashes in a plastic film of a certain thickness using a laser cutting machine; and forming the artificial eyelashes by submerging the plastic film with the cutting lines formed in a cutting solution contained in a cutting container; wherein the step of forming the artificial eyelashes is characterized in that the tip of the plastic film corresponding to the tip of the artificial eyelash is submerged in the cutting solution for a relatively longer period of time, thereby forming a sharp tip of the artificial eyelash.
