Burns may occur due to extreme heat from radio frequency. But this is only on some rare occasions. It is, therefore, essential to seek radio frequency skin tightening from a reliable provider. A reliable provider will only use RF skin-tightening equipment that the U.S. FDA approves –(Food and Drug Administration). The risks of getting burnt are reduced by using RF skin tightening with safety features.
