The nursing laws and rules allow a competent and appropriately trained registered nurse from applying eyelash extensions as an intervention based on nursing assessment, nursing diagnosis, or under the direction of an authorized health care practitioner. The registered 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.
