The nursing laws and rules allow a competent and appropriately trained licensed practical nurse to apply eyelash extensions under the direction of an authorized health care practitioner or under the direction and supervision of a registered nurse. The licensed practical nurse should use the Scope of Practice Decision Tree to determine if these activities are within the nurse's legal and individual scope of practice. The Food and Drug Administration (FDA) approves cosmetics. No color additives are approved by the FDA for permanent dyeing or tinting of eyelashes or eyebrows. False eyelashes and extensions, as well as their adhesives, must meet the safety and labeling requirements for cosmetics. See the Food and Drug Administration's website, Using Eye Cosmetics Safely, for more information.
