All home use facial rf or hifu devices will not melt away facial fat because there’s not one home use facial rf or hifu device can reach up to over 45 degree . Very weak . The hifu and rf administered by doctors or licensed practitioner can heat up to 62 degrees that’s when the risk of melting facial fat increases. The device you were showing silk titan would not even heat up to 40 degrees . Very minimal results when using it .
