Originally Contour threads received FDA approval in early 2006 which was quickly revoked due to the nature of the threads permanence. These threads were not “absorbable” and could not be removed once they were inserted. EuroThreads uses a biodegradable suture that has been FDA approved for decades in cardiovascular surgery. In 2015, the FDA approved the same suture for aesthetic treatments. Thread lifting can be used for treatments to the face, neck and body.
