Health Canada advises consumers and clinics and spas about the importance of using authorized absorbable threads for cosmetic thread lifts (e.g., nonsurgical facelifts). Using unauthorized threads or those meant for other purposes (such as wound closure or stitches) for cosmetic use may pose health risks such as nerve damage, skin irregularities, infection, pain, and bruising. Threads might break, move in the skin, or become exposed, causing temporary or permanent side effects. Health Canada is aware that various clinics and online retail platforms are promoting the use of unauthorized threads or threads that have been authorized for other uses for cosmetic purposes. Importing and selling unauthorized medical devices or advertising medical devices for indications not approved by Health Canada is illegal. When Health Canada identifies unauthorized products that may pose serious health risks, Health Canada takes appropriate action to prevent further distribution and informs Canadians. Actions taken by Health Canada may include seizing unauthorized products, taking action to remove illegal advertising, and working with the Canada Border Services Agency to help prevent further importation of unauthorized products. In addition, Health Canada is aware that do-it-yourself thread lifts are being promoted on social media and that untrained individuals are performing cosmetic thread lifts. These devices should only be implanted by a physician or used under the supervision of a physician, preferably in a healthcare setting.
